The passive infrared detector detects the motion of infrared light sources at the same wavelengths as those emitted by humans. Passive infrared detectors like this one are used in safety and automation applications. In the security area, motion detectors are integrated into alarm systems and used to turn on surveillance cameras. PIR motion detectors are also used to automatically turn on the light when people enter a room.

The two pyroelectric sensor elements allow the PIR motion sensor to see moving infrared light sources without ignoring background infrared radiation changes. A lens focuses the infrared light on the two silicone-coated sensor elements.
