PIR 20 Passive infrared motion detector Flexible and reliable Passive infrared motion detectors (PIR) are infrared detectors that detect the movement of people or other thermally radiating objects and trigger electric, optical or acoustic indication signals. These motion detectors work with temperature-dependent pyro sensors that react to infrared light with a certain wavelength, meaning that they react to human body temperature or thermal radiation from vehicles. Excellent integration options thanks to compact dimensions The small, compact design of PIR motion detectors makes them ideal...
