Heat Rises And So Should You: High And Low-Tech Ways To Keep Your Home Cool

Summer is definitely here and with that comes the sudden urge to keep yourself and your home cool. Heat can often make you feel frustrated, especially when you can’t seem to function and carry on as you would normally. However, it doesn’t need to cost you a fortune to keep your home cool this summer, we thought it was about time to share with you some of the low-tech and cost effective ways you can keep your home cool this summer.

Plant some trees

This is as low-tech as it will get, but trees are a natural air conditioner for your home. They let immense light in during the winter when they have shed all their leaves, but create amazing shade during the summer when the leaves are out and grown. This helps to keep your home and garden cool offering a natural block out to the sun.

Use an air conditioning system

More high tech than planting trees and possibly the easiest, and maybe most expensive way, of keeping your home cool is to use an air conditioning system. This will help to create a haven in your home when the outside temperature gets too much. However, it is important to ensure that you have a system that is working and your thermal dispersion flow switch is in good condition to ensure that your system is up to scratch. An air conditioning unit can also help to make sure you get a decent night’s sleep. After all, heat rises and can make bedrooms hot even when the sun has set.

Keep the curtains and blinds closed

This may be one of the simplest tips you will read, but there is much truth to keeping your curtains and blinds closed during the day. There are studies that show 30% of unwanted heat into your home comes from your windows. However, keep the blinds shut can help reduce temperatures throughout the day and subsequently make your home much cooler in the evening.

Sometimes it’s best to focus on your body temperature rather than the home

Many of ancestors survived hot summers without the need for gadgets and technology, especially things like air conditioning units. So why not take a leaf out of their book and focus on your own body temperature instead. Keep cool by keeping your body hydrated with water. This is essential to your well-being and your health during the hottest days of the year. Indulge in icy cold drinks and make sure you keep your fridge stocked up with colder beverages. You may also want to try running your wrists under cool water every few hours.  A major vein passes your wrist and it can be very effective to keeping your body temperature cooler.

Focus on your bed at night

Changing your sheets often will help to ensure that your bed stays fresh, but, of course, it isn’t a guarantee for keeping your bed cool. There are some amazing tips online that suggest filling up a hot water bottle and placing it in the freezer to ice up. Then, if you place it at the foot of the bed it can have a cooling effect on your feet. Other suggestions include putting your pillow and bed sheets in the fridge for a few hours to instantly give you that cooling sensation when heading into bed.

Control your home temperature via your phone

While this may be a gadget for the winter as well as the summer, it is now possible to control the temperature in your home via your phone. This can be a real game changer and also help you keep the costs down when it comes to running air conditioning and even your heating system in the colder months. It enables you to get your home cool before you get in, rather than walking into a home that can often feel like an oven when having been left alone in the heat all day. 

Let the night air into your home and allow it to circulate

During the summer months the chances are when the sun sets, the temperature will drop. This is the ideal time to open up all the windows in your home and let the night air circulate throughout. It is also advisable to do this early in the morning before the temperature begins to rise. It enables you to keep your home cooler for longer. After that, it could be a good idea to close off certain rooms. This can help keep your home cooler at the hottest points of the day.

I hope these tips help you when the sun is out.

The Basics of Building a Website

Read below to learn all about the ABCs of building your own website:

Set Goals

Committing yourself to building a website from scratch is just like committing yourself to most other ventures in life. You must have goals, a vision, and a long-term strategy for your site. Without these, your site will most likely go nowhere. Or you could spend all your money redesigning your site over and over again every time you change your mind. Therefore, write down the goals and hopes you have for your site. Make sure that these are realistic first.

Get Your Own Domain Name

Before you start the site design process, you must obtain your own domain name. Having your site hosted on someone else’s will not do, unless your target audience is extremely limited, to your family for example. Therefore, come up with a simple and memorable domain name for your site. Use an online tool to ensure that this name is not too similar to another site’s. Then get a domain extension, usually provided by the server you hire. When you hire a server, check their web reviews first.


You will first need to brainstorm design ideas for your site. You might come up with a thousand ideas or nothing at all. Get inspiration from acclaimed sites you can find online. Also, you must check out the sites created by the competition. See what they are doing, and make sure not to do something that looks awfully similar.

Open Source Design

You will mostly likely need a content management system (CMS) to design your site. Three are essentially two different kinds of CMSs: proprietary, which charge licensing fees from users, and free, which charge nothing for basic designs. Popular CMSs like WordPress are free. You can use such a service for your site to cut costs. However, if your site needs an advanced design or specific components, a proprietary CMS that has all the features you need will be worth the money.

Make Site Mobile Compatible

Most users browse sites on their handheld mobile devices. Therefore, if your site is not compatible with mobile phones, you are losing out on millions of potential visitors. Therefore, use a design template that is compatible with Androids and iPhones. You should also think about creating an app to complement your site.

Start Creating Content Early

The content on your site will be blog posts, pictures, product descriptions and so on. All this material should be prepared well in advance, so when the design layout is done, content can be uploaded instantly. Do not send your site online with missing content. You will gain a bad reputation even before you have started.

Often Ask “Why”

If you are adding or removing a component from your design layout, always ask ‘why’ first. Why is a good question to ask whenever you have to make a decision regarding your website? Doing so will minimise the risk of you making a mistake.

Hire Professionals Whenever Necessary

If you have no prior experience doing something, or if your skills are subpar, do not hesitate to hire a professional to get the task done appropriately. Spending a little money now on expert input is better than losing visitors in the future because of bad quality.

Before you go on about designing your own site, learn all of the above until you know them like the back of your hand.

Make Your Photos Incredible With These Handy Tips

Most of us use photos every week. We post them on social media to detail that fantastic weekend away. We print them out to give to family members as gifts. We even use them to evidence bad driving, antisocial behavior and everything that’s weird or wacky. Seeing is believing after all. So how can you make your photos better? Can your humble smartphone really be used to capture an image that could go viral?

There are a few standard rules of image composition that help us to create a great picture. The rule of thirds, where everything in the frame is clearly divided into three, is just one of them. But when it comes to social media and telling a story, it’s more about capturing that incredible moment. See the emotion and hit the button at the right time.

Context and perspective are also really important things to consider. Showing a woman smiling in the street means a lot more when you see the reason why. Perhaps she’s just accepted a marriage proposal? You need to show her partner down on one knee to get the whole story into a single image. Putting objects into context is handy if you’re trying to show something that isn’t normal. A close-up of a dent in your car means very little unless there is a familiar object next to it to show its size. A hand or a ruler gives us context about the scale of the damage.

Once you have captured your images, your work is not yet done. Now you need to edit the images. Crop out the unimportant edge of frame areas. Grade the colors to help convey the mood or occasion a little more. Remove problem areas, or edit them to improve them. Packages like Photoshop are the industry standard for this kind of work. Understanding the Photoshop interface isn’t always easy. Sometimes it’s best to take a short image editing class to help you along.

Altering the brightness and contrast can create incredible effects for your image. It can even alter the whole mood of your photograph. Of course, most of us use it to correct balance problems caused by the technology we used to capture the image. A smartphone held very steady can create incredible quality images. There are also plenty of options within your phone camera settings to alter the focus and look of the picture you create. It’s worth considering whether these are useful or if it’s better to use a pro software package in editing to tidy up what you capture.

Once you’ve finished touching up your image, it’s time to print it or post it online. Sometimes it can be really handy to print an image out at home or at work to distribute as part of a presentation or for someone who needs a hard copy. Posting the image online can give people the opportunity to print it out for themselves, or to enjoy it digitally.

However you use your digital photography, a little bit of editing can go a long way. Manipulating images can help you convey a mood or idea better. How do you take pictures?

Is A Virus On Your Computer Bugging You? Here’s How To Remove It!

There’s no denying that the World Wide Web is a useful resource. Millions of us go online every day to buy stuff or learn new things. We even use the Web to communicate with other people through social media.

The only downside of going online is the inherent risk of malware and viruses. There is a small community of hackers online dedicated to stealing personal data. There are even criminal gangs that attempt to extort money from unsuspecting web users.

As you can imagine, this is a big problem for anyone that uses their computer to go online. Windows is the operating system with the biggest market share. Because of that fact, it gets affected the most by malware and viruses.

If you’ve got a virus that’s bugging you and making your machine miserable, help is at hand! Keep reading to learn how to remove it:

Reboot your PC into Safe Mode

The first thing you must do is reboot your computer into Safe Mode. Why is this important? The answer is simple. Safe Mode boots up the Windows OS with only essential device drivers loaded. It also doesn’t load up any software you installed on your system.

Safe Mode is a useful way to take control of your computer when it has a virus or malware. Especially if the infection “takes over” your system and doesn’t allow you to do anything on it.

To get into Safe Mode, you need to press the F8 key once your PC has rebooted. You will then have a list of boot options, one of which is Safe Mode. Select that using your down arrow key and press the Enter key. Check out for further help.

Delete all temporary files

Once you’ve successfully rebooted into Safe Mode, you need to start the cleanup operation. The first step is to delete any and all temporary files on your system. The areas to target include your Recycle Bin and temporary Internet files.

You might not know it. But, malware and viruses often “load” from those locations on your PC. By deleting all temporary files, you can remove most infections.

Install a malware removal tool

Next, you need to check your system for other malware and viruses lurking beneath the surface. It’s a time-consuming process, and so it makes sense to use a malware removal tool. Its job is to automate the process and remove infections for you.

The most popular tool for the job is Spyhunter 4. You can read more about it at Another tool you can use is Malwarebytes.

Install some Internet security software

Once you’ve run the tool and removed the infections, reboot as normal into Windows. When you are sure the malware or virus is gone, I recommend installing some security software. There are scores of titles on the market that you could use. Examples include Norton Security and McAfee Total Protection.

The advantage of doing that is the software will block any future malware or virus infections.

Good luck!

Top Tips to Select a Tech Project Manager

When you start a tech project of any kind, it essential to have a project manager. A project manager is that person who’s going to be the point person, ensure everything moves smoothly, and serve as a centralized hub of communication in many ways. Project managers facilitate the process that goes into the development of anything related to technology, so how do you choose this person?

The list below represents some key criteria to consider as you select a PM for your next tech project.

Match Skills Appropriately

One of the first mistakes made when selection a technology project manager is the tendency to want to hire the person with the most skills, as opposed to someone with the right skills. Even if a candidate has broad experience and expertise, that doesn’t necessarily mean they’re going to be the right fit. When matching skills, try to find the person that has what reflects most closely your project requirements. Don’t become so blinded by an incredible resume that you forget what’s critical to the core of your project.

Hone in On Soft Skills

When you’re looking for a technology project manager, there can be a tendency only to look at their skills or their training and education. Unfortunately, this is detrimental because there is a lot more that goes into managing a project than simply have the technical expertise. Think about soft skills. Some of the important characteristics to look for in a project manager include strong communication, empathy, and organization. You also want to look for someone who seems to have a good ability to look at the long-term picture, see where obstacles may exist, and who is willing to be flexible enough to adequately address challenges that arise, even if they’re unexpected.


When it comes to technology projects, there are a lot of different approaches that can be taken. One of the most popular is the agile methodology, but there are specific distinctions even within this broader category. Consider how potential project management candidates approach their work, and what training or certifications they might have. One of the most valuable certifications when it comes to technology project management is DevOps training, which refers to a framework for integration communication, collaboration, and automation to improve workflow between developers and IT professionals.

Consider Other Team Members

A project manager is going to be inherently intertwined with the members of his or her team throughout a tech project, so when you’re choosing someone, make sure that you’re also considering these people who will be working under the manager. Project managers need to be able not just to work with the people that report to them, but also effectively lead them and inspire them to stay on time and budget with the project.

The person you select to manage your technology project is often going to be the link between your organization and the final product. This person is going to determine how smoothly the project moves along, how well it stays on course time-wise, and whether or not it adheres to budgetary restrictions.

Tricks To Improve Your Printed Picture Quality

Digital photography replaced more traditional methods a long time ago. There’s no more winding up film or long waiting times for physical pictures to be developed. Now of course, we’re seeing 3D printers in every industry! However, like a lot of people, you might like to have physical pictures for displaying around the house. Sometimes, our pictures can come out looking a little worse than we hoped. Here are some ways you can improve the quality of your printed pictures.

Firstly, you could try adjusting the pixels per inch on your photos. The resolution on your print preview will have a pretty significant impact on the way your printed pictures turn out. The less pixels that are packed into a picture, the sharper the end result will be. The resolution a screen is able to display is actually a mere fraction of what a monitor can deal with. If you’re downloading an image off of Facebook or another online source, it will probably pack in under 100 pixels per inch. If you’re looking to print off a photo and frame it, you’ll want to aim for around 300. Before printing an image, open the print options and adjust the PPI. Just be aware that upping the pixels per inch can shrink the image size.

If you’ve tried printing off pictures without changing a thing, then you may have noticed that certain hues look faded, and far less bright than the preview. If this is your main problem, then you might want to try playing around with different ink and toner cartridges. I know that the instructions with your printer probably recommend using their brand and their brand only for the best results. While this is true of some models, you shouldn’t take it as a fact. I’ve found that some cheap printers perform fantastically when they have a more high-end ink. Similarly, you may be able to find an expensive printer that works well with cheap cartridges. Experiment a little, and eventually you’ll find a combination that gives great colour quality.

Finally, make sure you’re maintaining your printer properly. This is an especially important point if you’re using an inkjet model. These have delicate little nozzles which can easily become clogged with ink and debris. You’ll need to check and clean these regularly depending on how much you use your printer. Some people run into this problem, but continue printing their poor-quality images and documents, oblivious to what the issue is. At least once a month, you should make a point of running your print head cleaning utilities. If you don’t use your printer all that much, set reminders to print on it around once a week. Like a lot of machinery, printers need to be used to keep them in good working condition. Leave it alone for weeks at a time, and it can easily fall into disrepair.

Take this advice, and I’m sure you’ll see an immediate improvement to the quality of your printing. Having to put up pixelated or faded pictures is not only frustrating, but also totally unnecessary!

How To Make More Money From Your Website

If you have a website, then it’s a great way for you to make money. Selling things online can lead to lots of profits. And, there are ways for you to take things further, and start earning even more. If you want to know how to make more money from your website, then read the article below:


The easiest way to make more money from your website is to advertise on it. If you haven’t already got ads on your site, then you need to get some. The represent a great way for you to generate secondary income. And, if you have some, then maybe you can add more, or find better ones? Look for advertising services that pay you more for the ads they put on your site. Likewise, you might find more success by contacting companies personally. Get into contact with people and let them know you’ve got space for them to advertise. Maybe you can offer them a priority contract? Give them the biggest ad space on your homepage, the place most people will see it. This entices them to pay more, and you earn some extra money.

Improve CRO

Conversion rate optimization (CRO) is crucial for making money. If you have good CRO, then more of your visitors will become customers. It’s something that I think a lot of people don’t understand or tend to forget. They put all their efforts into increasing web traffic and don’t think about CRO. You could have thousands of people visiting your site each day. But, out of these people, only one hundred could become customers. By improving CRO, you could change this so five hundred become customers, or even more. Naturally, getting more customers, every day, leads to an increase in money made. Improving CRO can be very technical and involves lots of research and testing. You need to do things like AB split testing and conduct data analysis. But, the result of all this is that you have a website that functions a lot better. Instead of wasting your impressive web traffic, you’re making more money, every day.

Start A Blog

Personally, I think that everyone should have a blog on their website. They’re just so beneficial and make your life a lot easier. With a blog, you can write articles and post content relevant to your website. How does this help you make more money? Well, for starters, you could write sponsored blog posts. Companies could get in contact with you and pay you to write something promoting them. This is a handy way to make some extra cash. But, I advise you to be careful with the sponsored posts you accept. The last thing you want is to promote a rival company selling the same things as you. Furthermore, a blog can help with the first two ideas too. You have more space on your website by adding a blog. Therefore, more places to put adverts. Also, people will come to your blog to read your articles. Once there, you can persuade them to buy things during the articles. As a result, your CRO can increase.

Use this advice and you’ll soon maximize your earnings!

How to Make Your Website More Appealing to Visitors

Every modern business requires a website. A business without a website does not have much credibility. In this tech savvy day and age, such a company might as well not exist. The majority of people who want information about your business will head directly to your website with their queries.

Of course this means that your web site must also be appealing to users. It must encourage them to visit your site and to explore further once they are there. This is where the blueprint of the site comes into play. To ensure that you create the best website possible, hire a Pattaya web design company that will build the site for you. This way your website will have structure and be more aesthetically appealing. There are still some things you should monitor, however, as the site is compiled:

Organize Your Pages

Your potential consumers can only benefit from your site if they are able to make sense of it. To make the website more appealing, it needs to be organized in a logical manner. You should figure out the structure that you want your pages to follow. Make sure that it will make sense to your users, not just to you. Have several directories, and even sub-directories for maximum organization.

Your homepage should provide newcomers with a brief outline as to your company’s purpose. They must be able to know exactly what products you are selling or services you are providing after reading that page. This page determines whether or not a user will go further into a site so make it good. If you frequently add articles or announcements to your site, it is better if you archive them according to the date. It will make the site less disorderly.

Create a Navigation System

When users visit a site, they usually have a specific goal in mind. There is a certain aspect of your business that they would like to view. You should make it as easy as possible for your visitors to find what they are looking for. This is why an appropriate navigation system is an important part of your website. This will help your user to maneuver your site.

Menu lists, tabs, and site maps are all excellent ways of guiding your potential customer through your platform. They will be able to quickly and easily locate what they are looking for. You can further improve on this function by having a search option. This will allow the visitor to type in the search term and have it highlighted on your website.

Make it Appealing

Packaging matters. If your website does not look nice or looks like it was thrown together, people will not want to visit it. The quality of your content should be reflected in how you present it. The design of your site should be based on the product or service that you are providing as well as your target audience.

If you want to cater to an older, more distinguished audience, your site should be more professional. If your intended audience is younger and your company feel is more fun, have a relaxed site with engaging videos and images. Remember that it is the appeal of your website that will get you those initial visitors.

Websites are an important aspect of your business and should be treated as such. You should spend a considerable amount of time and effort perfecting your site. It is the platform through which people will view your entire company.

Smart Sensor Technology – Radio Frequency Sensors

Thе RF Smart Monitor System іѕ designed tо allow thе user tо remotely collect machine vibration аnd temperature data wіthоut thе need fоr cabling. Thіѕ system, whісh іѕ designed tо monitor а wide variety оf machine components, consists оf following things:

  • Battery-powered RF Smart Sensors, whісh аrе placed оn machine components аnd collect/process vibration аnd temperature data,
  • One оr more RF Transceivers, each оf whісh іѕ аblе tо remotely communicate wіth uр tо 64 RF Smart Sensors via radio,
  • RBMware 4.20 оr lаtеr tо create thе database аnd analyze thе Smart Sensor data аnd,
  • A CSI Model 2120 оr Handheld Personal Computer (HPC) tо communicate wіth RBMware аnd thе RF Transceiver.

Thіѕ system іѕ designed tо smoothly integrate wіth RBMware 4.20 оr lаtеr. Databases аnd routes аrе created іn RBMware аnd downloaded tо thе 2120 оr HPC. Four measurement points (vibration, PeakVue, temperature, аnd battery life) аrе generated wіth each RF Smart Sensor created іn RBMware. Once а route has bееn created, thе user downloads thіѕ information into а 2120 оr HPC. Thе user thеn connects thе 2120 оr HPC tо thе RF Transceiver аnd requests data frоm thе remotely located RF Smart Sensors specified іn thе route. Thе RF Transceiver thеn transmits а message tо thе selected RF Smart Sensors directing thеm tо collect аnd process thе data based оn analysis parameters established іn RBMware. Whеn complete, each RF Smart Sensor remotely transmits vibration, PeakVue, temperature, аnd battery life data bасk tо thе 2120 оr HPC via thе RF Transceiver. Thе collected data іѕ thеn downloaded tо RBMware fоr trending аnd analysis.

Thе RF Smart Monitor System іѕ іtѕ wireless remote access capability. Thіѕ іѕ accomplished via а robust form оf radio communications known аѕ spread spectrum. Thіѕ digital modulation technique has bееn widely used due tо іtѕ immunity tо interference. Spread spectrum systems аrе аlѕо very unlіkеlу tо cause interference wіth оthеr radio systems, even оthеr spread spectrum devices. Interference issues аrе minimized wіth thіѕ technique bесаuѕе thе signal оf interest іѕ encoded wіth а lengthy digital pattern thаt approximates white noise. Cоnѕеquеntlу, thе resulting signal looks like low-energy, band-limited white noise thаt саn оnlу bе interpreted bу а receiver thаt uses thе same digital pattern tо decode thе signal. Whіle thе signal іѕ rеlаtіvеlу low power, long range communication іѕ attainable due tо thе frequency оf operation (2.4 GHz). Thе typical range achievable bеtwееn аn RF Smart Sensor аnd аn RF Transceiver іѕ approximately 300 feet. In addition, thіѕ form оf communication does nоt require line-оf-sight bеtwееn RF Smart Sensors аnd RF Transceivers. Thіѕ allows thе RF Smart Sensors tо bе placed аt thе most ideal locations оn thе machine tо maximize sensitivity tо vibration аnd temperature signals. Anоthеr advantage оf thіѕ modulation scheme іѕ thаt no site license іѕ required.

During thе beta test phase оf thіѕ product, RF Smart Monitoring Systems wеrе evaluated аt several industrial facilities оn а variety оf machines. One prime application оf thіѕ technology highlighted during thе testing phase іѕ thе uѕе оf thіѕ technology оn machines thаt аrе еіthеr hard оr dangerous tо access. Machines іn elevated locations (i.e. cooling towers) whеrе thе analyst wаѕ required tо climb а ladder tо reach thе site, оr machines located іn hazardous locations (i.e. Class I, Div. II areas) аrе examples оf ѕuсh а scenario. Anоthеr uѕе оf thіѕ technology іѕ оn machines thаt have а range оf motion (i.e., robots, accumulators, machine tools, cranes, еtс.), whеrе gaining access іѕ difficult аnd routing cables іѕ nеаrlу impossible. Machines thаt fall іn thіѕ category often аrе nоt analyzed fоr extended periods оf time since thеу muѕt typically bе taken оut оf service prior tо being surveyed. Aѕ thіѕ technology becomes widely used, оthеr unique applications wіll undoubtedly bе uncovered. In fact, thе beta program highlighted new concepts thаt аrе now under consideration.

Capabilities оf thе RF Smart Sensors

Thе RF Smart Sensor consists оf:

  • A high quality 10 mV/g accelerometer аnd temperature sensor
  • Analog circuitry tо condition thе vibration signal аѕ wеll аѕ generate а PeakVue Signal
  • Digital circuitry tо process thе vibration аnd temperature signals
  • An energy аnd power dense lithium C-cell battery fоr long life

RF Smart Sensor battery life under normal conditions іѕ expected tо bе one year оr greater, even wіth а full set оf data being collected once реr day. In addition, thіѕ device іѕ mechanically designed tо withstand thе harsh conditions encountered іn typical plant environment. Even wіth аll thе functionality built into thе RF Smart Sensor, іt іѕ оnlу approx. 4″ tall аnd 2.5″ іn diameter.
In terms оf measurement point setup, thе RF Smart Sensor іѕ capable оf thе following:

  • Vibration data displayed іn acceleration, velocity, оr displacement,
  • Pre-set sensor power оn/off, measurement point sensitivity, аnd auto-ranging,
  • Single analog integration аnd double digital integration, аnd
  • Pre-set analog оvеrаll mode override.

All оthеr measurement point setup options іn RBMware аrе supported іn thе usual manner. In terms оf analysis parameter setup, thе RF Smart Sensor has thе following capabilities:

  • A series оf pre-set Fmax values ranging frоm approx. 39 Hz tо 9375 Hz (RBMware аnd thе 2120 plotting functions wіll select thе nearest Fmax whісh exceeds thаt оf thе RF Smart Sensor).
  • Uр tо 1600 lines оf resolution, ten averages, аnd twelve analysis parameters (Hz INT, Order INT, HFD, Hz vHFD, MP Wave, P-P Wave, аnd Crest), аnd
  • Analog preprocessing wіth а fixed high-pass filter setting оf 2.5 KHz.

Note thаt thе RF Smart Sensor Fmax values іn Hz аrе: 39.06, 58.59, 78.13, 117.19, 195.31, 191.97, 390.63, 585.94, 781.25, 1171.9, 1562.5, 2343.8, 4687.5, 6250.0, аnd 9375.0. Alѕо note thаt spectral weighting, 1/3 octave analysis, SST, special time waveform collection, аnd demodulation іn thе envelope demodulator аrе nоt supported. All оthеr analysis parameter options іn RBMware аrе supported іn thе usual manner.

Finally, supported alarm limit set unit codes аrе VELOC, DISPL, ACCEL, HFD, TEMP (оvеrаll оnlу), W-ACC, аnd W-VEL. Additionally, оnlу thе four absolute alarms аrе supported fоr thе alarm type. All оthеr alarm limit setup options аrе аlѕо supported. In thіѕ way thіѕ article dеѕсrіbеd RF Smart sensors system, specifications, advantages оf thе modulation technique called spread spectrum.
