From the project

The Automatic AC Switch Using PIR Sensor is an electronics project designed to automatically control an electrical load based on human motion detection.

The Automatic AC Switch Using PIR Sensor is an electronics project designed to automatically control an electrical load based on human motion detection.

The Passive Infrared (PIR) sensor detects movement within its sensing range and provides a trigger signal to a switching circuit. The switching circuit controls a relay, which can be used to switch an AC-powered load such as a lamp or other suitable appliance.
