Automatic Motion Detector Light Control System

Description

This project is an automatic light control system based on a PIR motion sensor and relay module using Arduino. The PIR sensor continuously detects human movement in the surrounding area. Whenever motion is detected, the relay module automatically turns ON a 220V AC bulb. After a few seconds of no movement, the bulb turns OFF automatically to save electricity.

• This system is useful for home automation, smart lighting, staircases, parking areas, corridors, security lighting, and energy-saving applications. It provides automatic operation, convenience, and efficient power management.
