Infra-red is an electromagnetic wave who wavelength is between 0.75 microns to 1000 microns (1 micron = 1µm). Since infra-red is out of visible light range, we can’t really see IR with naked eye. However, there is a method to “see” IR which will be shown later on. Some of the...

That is to say, they don't use mercury (like old thermometers), bimetallic strips (...

Weather stations, room monitoring, or just to check the temperature of a part and trigger a fan, are some typical applications that require temperature sensors.I discovered an advertising on a website about a very cheap ...
