Fuzzy Logic-Based Control System for Solar Street Lighting

Solar-powered street lighting is a street lighting system that utilizes solar energy as its power source. In Indonesia, public street lighting accounts for the one of the largest electricity consumption and has been increasing over the years. In this paper, researchers aim to develop a fuzzy logic-based control system supported by the use of an ultrasonic sensor HC-SR04 for adaptive lamp activation. Furthermore, this system utilizes solar panels as its power source, enabling it to be self-sustaining and ensuring continuous energy supply. The testing of light intensity and battery discharge demonstrates the low power consumption with significant power efficiency in the self-made street lighting system. The fuzzy logic testing between the device and simulation yields an average error of 0.05% for the PWM percentage output and an average error of 0.08% for the dimming output.
