What is SAR Value and how to check?

Do you know what is SAR Value? Do you use mobile phones a lot? If the answer to this question is yes then you must know about SAR Value. Because like a phone bell, it is a danger bell for us. And some wise man said that it is good for us to be alert to danger. As we all know that nowadays mobile phone has become a part of our life. It is time for us to get acquainted with the danger from it.

Mobile communication requires various electromagnetic waves. To send and receive such signals, an antenna is required, with the help of which transmission of these waves (or signals) takes place. Whenever there is a transmission, some percentage of the signals radiate to about 10-20% of the atmosphere. This is because there is some power in these signals which dissipate in coming to know, which is also called mobile radiation. This radiation level depends only on the usage of mobile. SAR (Specific Absorption Rate) Value is used to control this Radiation Level. So today we will know what is this SAR value (what is SAR value in Hindi) and why is it so important. Then what is the delay? Let's start.

SAR Value has a full form. Specific Absorption Rate (SAR) is a criterion with the help of which we can measure how much Electromagnetic Waves are being radiated while using any electronic device that our body Is being absorbed by. To measure this rate, it is seen that how much power is absorbed in the Tissue of our weight. Its Standard Measurement is measured in Watts per kilogram (W / kg). This radiation mainly affects the two parts of our body the most, our head and the lower part of the head ie the torso. Sir, because while talking in the phone, this part is most close to that radiation field.

In order to standardize these radiation, the government has made certain fixed standards, which shows that above this standard, no mobile manufactures can make or make their own mobile and leave it in the market. These include the standard items of India and US which is 1.6 Watt per Kilogram (W / kg), which has been made with 1 gram of Tissue. At the same time, according to European standard, 2 Watt per Kilogram (W / kg), which has been made with 10 gram of Tissue.

There is a lot of misconception among people that mobile which has low SAR value is right for us, but I want to tell you that SAR value is low or high but it is very dangerous thing for us. Yes or the fact is that the lower the SAR value, the less the danger of a human being. But remember that how long you use that mobile can also be judged by its damage. The SAR value is nothing more than the absorption rate of that radio frequency waves.

How to check SAR Value
As we all know that all mobile phones have specific SAR value. But now the matter arises, how to know it, so do not panic, it is absolutely easy to find out, you just have to dial in your mobile * # 07 # and your mobile SAR value will be displayed in your screen in front of you.

How SAR Testing is done
It must have come to your mind that how this SAR testing is done. So, for your information, let me tell you that for this, a model like our body is prepared in which some things like our Tissue are inserted so that an actual Human model can be made. After that the radio frequency (RF) is tested in our various organs to check their absorption rate.

That radiation is tested from different distances from both sides of our head to find out how far the maximum radiation is absorbed in our head. After doing all such tests, a detailed report of them is prepared, in this report all the highest SAR value all frequency band is mentioned. After this, it is sent for Government Authorization and then if approved, the model of mobile is ready to enter the market.

What is Metro Train and how does it run?

Everyone knows what is this Metro Train or what is Metro Rail, but do you know how this shape works? If not, then you must read this article. As we know our country is moving forward on the path of progress, its population is increasing more. Because of being a developing nation, there are many difficulties in its progress, in such a situation, problems of transportation or transportation are also emerging. Our scientists are working day and night to solve all these problems. Metro Rail has been a major contributor to providing traffic to the growing population, with the help of this many people are able to go from one place to another very easily. Since it carries traffic in underground tunnels in most places, it also has little problem of traffic. If seen, the metro rail in our country has been around for 25 years, but its increasing need has made it a very useful medium for traffic. So today we will know what is this Metro Train or what is Metro Rail and how does it work. Then what ...

Image What is stabilization and how does it work?

Do you know what this image stabilization is (what is image stabilization in camera) and how it works, if yes then it is a good thing and if not then this article is for you. Like we know that sometimes when we are clicking a photo, sometimes the picture becomes a bit blur or blurry because it is because our hand may be slightly shaken while the photo is being pulled, due to which the picture is complete Clear is not drawn. It hurts our heart a lot. But what should we do, we are an honest person, and humans make mistakes. Have you ever thought that despite something like this happening in mobile, Picture comes clear. How does the technology behind it work? If you want to get complete information about all this, then this article is Image Stabilization and how it works. Because today I am going to tell you about this topic. Then what is the delay? Let's start. Image Stabilization (IS) This is a method with which we can correct the habit of taking blurry pictures to a great extent. I...
