Automatic Street Lights Using Arduino

The increasing demand for energy-efficient solutions has led to innovative technologies like automatic street lighting systems. This research paper presents a comprehensive study and implementation of a cost-effective automatic street light system utilizing LEDs, ultrasonic sensors, 1k resistors, Arduino Uno, and jumper wires. The system operates by detecting vehicles using ultrasonic sensors, which triggers the LEDs to illuminate, thereby conserving energy when no vehicles are present. This paper discusses the design, working mechanism, advantages, challenges, and future applications of the system. The study demonstrates how this solution contributes to energy conservation and improved street lighting management.
