Passive Infrared (PIR) sensors- are small, low powered and cost effective, they sense a change in temperature between the background and a warm heat emitting body. Everything emits low-level radiation, the pyroelectric sensor detects the differing levels of infrared radiation and thus senses movement or presence. Also called presence detectors these might be used within rooms such as offices, cubicles such as in washrooms or on the underside or desks or tables to detect occupancy.
