Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to provide the detailed discussion on PIR Sensor Arduino Interfacing. PIR basically stands for Passive Infrared Sensor. Basically PIR is an electronic equipment which is often used to measure the infrared light radiating from the different objects in their field of view. It detects the infrared energy released from animals as well as from human beings, when this energy is higher than the certain threshold level PIR sensor shows an indication correspondingly. The energy detected by PIR sensor is usually in the form of heat i.e. emitted by humans as well as from animals.
We can also test and verify our results in Proteus using PIR sensor. I have already shared ...
