Passive Infrared Sensor (PIR) working with Applications

PIR Sensor. The detected radiations are converted into an electrical charge, which is proportional to the detected level of the radiation. Then this charge is further improved by a built in FET and fed to the output pin of the device which becomes applicable to an external circuit for further triggering and amplification of the alarm PIR sensor …
