How it works:
Interfacing a Passive Infrared (PIR) sensor with a PIC16F877A microcontroller involves connecting the sensor to the microcontroller and programming it to detect motion.
PIR sensors detect changes in infrared radiation within their field of view. When an object moves within this field, the sensor detects the change in heat and triggers an output signal.
