WebA Passive Infrared (PIR) sensor detects changes in infrared (heat) radiation. The PIR works by accumulating thermal energy from the surrounding area, which is then processed to produce an output signal proportional to the rate of thermal energy being received at its sensing face. This type of motion detector may be thought of as a heat-seeking ...
