Energy Efficient Lighting System Using LEDs and Sensors

Abstract: This paper presents an energy-efficient lighting system that integrates Light Emitting Diodes (LEDs) with motion (PIR) and ambient light sensors (LDR). The system optimizes energy consumption by controlling the lights based on occupancy and ambient light conditions. The use of LEDs ensures low power consumption, while the sensors help reduce unnecessary energy usage. The system, managed by a microcontroller, adjusts the LED brightness or turns the lights off when no movement is detected or when ambient light is sufficient. The proposed system is designed to offer energy savings without compromising lighting requirements.
