Automatic Street Light System

This project is an Automatic Street Light System that automatically turns the street light ON during night time and OFF during day time using an LDR sensor. The main aim of this project is to save electrical energy and reduce manual work.

Project Description

The system uses a Light Dependent Resistor (LDR) to sense the surrounding light intensity. When the light intensity is low (night), the street light turns ON automatically. When the light intensity is high (day), the street light turns OFF automatically.

Components Used

• LDR (Light Dependent Resistor)
• Arduino / Microcontroller
• LED / Street Light
• Resistors
• Breadboard
• Connecting Wires
• Power Supply

Working Principle

• LDR senses the ambient light
• If light intensity is low → Street light turns ON
• If light intensity is high → Street light turns OFF
• This process continues automatically without human intervention

Applications

• Street lighting
• Parking areas
• Campuses
• Smart city projects

Conclusion

This Automatic Street Light System is simple, cost-effective, and energy efficient. It helps in reducing electricity wastage and supports automation.
