Passive infrared sensor Wikipedia

A passive infrared sensor is an electronic sensor that measures infrared light radiating from objects in its field of view. They are most often used in PIRbased motion detectors. PIR sensors are commonly used in security alarms and automatic lighting applications. PIR sensors detect general movement, but do not give information on who or what moved. For that purpose, an imaging IR sensor is required. PIR sensors …

Understanding Active Passive Infrared Sensors (PIR) and ...

· An IR emitter shoots out a beam of light, facing an inline receiver. If nothing is in the way, the receiver sees a signal. If the receiver fails to see an IR beam, it detects that an object is between the emitter and the receiver, and therefore present in the monitored area. One variation of the standard active IR sensor uses an emitter and receiver facing the same direction. The two sit very close to each other …
