Pollutant Control

Pollution is a very important issue. The reduction of pollution and greenhouse gases has become a major priority for parliament. We need to be able to monitor levels of pollution, in order to monitor the situation. This is where the pyroelectric comes in.

Pyroelectrics, as shown previously, are excellent detectors of IR radiation. Therefore, they make perfect devices for testing the level of IR radiation that passes through a gas sample. As the wavelength at which a gas absorbs usually uniquely identifies that gas, this makes an excellent means of detection.

See below for the mechanics of this:
