Passive Infrared Sensor (PIR) working with Applications

2014-09-10· 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.
