This study presents the design and implementation of an efficient light-controlling system leveraging the combined capabilities of a Passive Infrared (PIR) sensor and a Light Dependent Resistor (LDR). The integration of these sensors aims to create an intelligent lighting solution capable of dynamically adjusting light levels based on human presence and ambient light conditions. The system addresses the need for energy-efficient lighting by activating or modifying illumination only when required, thus minimizing unnecessary energy consumption. The PIR sensor detects human motion, enabling the system to activate or adjust lighting in response to occupancy. Complementing this, the LDR measures ambient light levels, allowing the system to optimize illumination according to the natural lighting available. The synergy between these sensors results in a smart, adaptive lighting system that not only enhances energy savings but also provides a comfortable and convenient user experience. Key features include customizable settings to accommodate individual preferences, potential integration with broader smart home or building automation systems, and enhanced security through motion-triggered lighting. The study evaluates the system's performance in terms of energy savings, user satisfaction, and adaptability to various environments. Results indicate a promising reduction in energy consumption, contributing to sustainability goals and cost efficiency. The system's adaptability and potential for integration with modern technologies underscore its applicability in diverse settings, ranging from residential to commercial and industrial environments. The findings suggest that the efficient light-controlling system using PIR sensor and LDR offers a practical and user-friendly solution for achieving intelligent and sustainable lighting in today's dynamic and energy-conscious world.
