Abstract

The integration of intelligent systems into lighting and security is essential for enhancing efficiency, reducing energy consumption, and improving safety. Traditional systems often suffer from excessive power usage and delayed threat detection, leading to security risks and wastage. This research presents a Smart Lighting and Security System Using an Intelligent Controller, integrating a power supply, relay, light, 16×2 LCD, buzzer, PIR sensor, and Light Dependent Resistor (LDR). The system automatically controls lighting based on ambient light levels and human presence. The LDR detects natural light intensity, while the PIR sensor identifies motion, activating lights only when necessary. A buzzer alerts in case of unauthorized movement, and the 16×2 LCD provides real-time status updates. This IoT-enabled system ensures minimal manual intervention, optimizing energy use and reinforcing security. Suitable for residential and commercial applications, it offers a cost-effective,
