Passive infrared sensor - Wikipedia

Typical residential/commercial PIR-based motion detector (PID). 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. PIR sensors are commonly used in security alarms and automatic lighting applications.

Difference Between Position Sensor, Motion Sensor and ...

An IR sensor will not only measure the heat of an object, but also detects the motion. These sensors measure infrared radiation, rather than emitting it, so it is called as a passive IR sensor. Generally the infrared spectrum will radiate some form of thermal radiations which are invisible to our eyes and that can be detected by an infrared sensor. IR Sensor IR Sensor. The emitter is simply an ...
