A passive infrared sensor (PIR sensor) is an electronic sensor that measures infrared (IR) light radiating from objects in its field of view. They are most often used in PIR-based motion detectors.

(Passive InfraRed sensor) A device used to detect motion by receiving infrared radiation. When a person walks past the sensor, it detects a rapid change of infrared energy and sends a signal.

While PIR sensors are inexpensive, radar technologies are decreasing in cost and becoming more compact and simple to design. Radar solutions can range from simple motion detection to complex imaging ...
