Solar Powered LED Street Light with Movement Detection and Intensity Control

This proposed solar-powered LED street lighting prototype project is an eco-friendly option to improve energy efficiency with sufficient lighting for enhanced human environments’ safety and visibility. To this end, a prototype was built by using a Zybo Zynq-7000 development board, BC547 transistor, TP4056 battery charger, Light-Dependent Resistor (LDR), chargeable battery, LED and resistors as a proof of concept using FreeRTOS task scheduling and priority management. The system’s sensors track ambient light levels and movement to intelligently modify the LED lights' brightness by dimming the light during low vehicles or pedestrians-related activity to conserve energy and immediately brighten upon detecting movement. With the goal of maximizing solar energy usage and minimizing waste, it extends battery life and improves overall system reliability during low-demand periods, thus lowering maintenance and operating costs. The proof of concept suggests a simplistic solution to address energy saving and urban lighting sustainability by utilizing solar energy and incorporating smart control mechanisms, paving the path towards more resilient and ecologically conscious cities. For future research, performance indicators like lighting effectiveness, energy savings, dependability, and user happiness can be proposed to assess the system's viability and suitability for broad implementation.
