Passive Infrared Sensors /PIR Sensors Applications
Passive Infrared sensors or PIR sensor is an electronic device that detects infrared light radiating from an object. This object could be human or animal. It does not emit waves like an active sensor since it is a passive sensor. Instead, it measures any significant increase in the energy level within its field of view.

Underneath the lens is the infrared sensing ...
Passive Infrared Sensor (PIR) working with Applications
Passive Infrared Sensor (PIR) The term PIR is the short form ofthe PassiveInfra Red. The term “passive”indicates that the sensor does not actively take part in the process, whichmeans, it does not emit the referred IR signals itself, rather passively detects the infrared radiationscoming from thehuman body in the surrounding area. PIR Sensor. The detected radiations are converted into an ...
