Automatic Security Light System Using PIR Sensor
Subject area: Science,Engineering and Technology · Area of research: PIR-Based Security Lighting Systems

Abstract
The Automatic security light system is designed to enhance safety and reduce energy consumption by automatically controlling lighting based on human presence and ambient light conditions. The system primarily uses a Passive Infrared (PIR) sensor to detect motion and a Light Dependent Resistor (LDR) to sense surrounding light intensity. When motion is detected in low-light or night conditions, the system automatically switches ON the security light, and it turns OFF after a predefined time when no motion is detected. This eliminates the need for manual operation and ensures efficient use of electrical energy.The proposed system is simple, cost-effective, and reliable, making it suitable for residential buildings, streets, parking areas, and industrial premises. By providing automatic illumination only when required, the system improves security while minimizing power wastage. The Automatic Security Light System demonstrates an effective solution for smart lighting applications in modern security and energy-saving systems.
