SIMULATION AND CONSTRUCTION OF KEYPAD-BASED SECURITY LOCK
Abstract
ABSTRACT
The rising demand for efficient and sustainable energy solutions has increased the need for improved solar energy harvesting technologies. This project focuses on the “design and construction of a single-axis solar light (LEDs) tracking system” aimed at maximizing the capture of solar radiation for enhanced lighting performance. The system uses a Light-Dependent Resistor (LDR) based sensor mechanism to detect the direction of maximum sunlight and automatically adjusts the position of the solar panel along a single axis. An electronic control unit, comprising a microcontroller, driver components, and a DC motor, enables smooth and accurate panel movement throughout the day. Energy harvested is stored in a rechargeable battery and used to power LED lamps for nighttime illumination. The developed prototype demonstrates improved efficiency when compared to a fixed solar lighting system, as the tracking mechanism increases exposure to direct sunlight, thereby enhancing energy storage and lighting duration. The system is low-cost, energy-efficient, and suitable for small-scale lighting applications in rural and urban environments. Overall, the project shows that single-axis tracking significantly improves solar lighting performance while maintaining simplicity and affordability.
