Smart Street Light System

The Smart Street Light System is an innovative Arduino-based project designed to demonstrate how automation and smart sensing can make street lighting more efficient and energy-saving. It combines Arduino, LDR sensors, ultrasonic sensors, and LEDs to create an intelligent lighting system that responds to both environmental conditions and nearby movement.

The LDR sensors detect the surrounding light intensity and help determine whether it is day or night. During low-light conditions, the system activates the street lights. The ultrasonic sensor detects the presence of people or vehicles near the lights, allowing the LEDs to operate intelligently based on movement.

This hands-on project helps students understand the practical applications of Arduino programming, sensors, automation, electronics, and energy conservation. It is an excellent STEM activity for learning how smart technologies can be used to build more sustainable and efficient cities.
