A significant quantity of electricity is wasted by the traditional street light system which is a potential electricity consumer. The amount of electricity consumed remains constant and unaffected by the volume of traffic. This project is to save electrical energy by detecting the vehicle movement and by increasing the intensity of the streetlights ahead of it and simultaneously decreasing the intensity of the lights. A smart street light system using photoresistor and Arduino can be designed to optimize energy consumption by adjusting the brightness of the streetlights according to the ambient lighting conditions. The system consists of a photoresistor that detects the ambient lighting conditions and an Arduino board that controls the intensity of the streetlights. The system works by measuring the resistance of the photoresistor, which changes according to the amount of ambient light. The Arduino board receives this data and adjusts the brightness of the streetlights accordingly. For example, during the day when there is ample sunlight, the streetlights can be dimmed or turned off, saving energy. At night or during cloudy days, the streetlights can be adjusted accordingly.
