What is PIR motion sensor?

PIR Sensor Full Form Is Passive Infrared Sensor. It Is An Electronic Appliance Measures Infrared Radiation From Objects In Generated Field By PIR Detector. Sometimes It Called PID – Passive Infrared Detector.

How PIR sensor works?

It Detects Changes In Amount Of IR Radiation, Which Is Depends Upon The Outside Characteristics And Temperature Of The Objects In Front Of Detector. It Means If Human Or Animal Will Come In Range Of Detector It Will Detect Movement Because Live Body Eliminates Warm Energy In Form Of IR Radiation. So It Will Give You Signal By Light Or Alarm When Any Live Object In Front Of PIR.
