Solar Powered Automatic Street Light System

Abstract: Street lights play an essential role in ensuring the safety of any neighbourhood. Possessing proper functioning street lights is a sign of a well-maintained and safe neighbourhood. On the other hand, street lights are one of the significant power-consuming systems in our country. More innovations can be adopted into the traditional street lighting system. One of the ways to implement efficient power consumption is by incorporating the Internet of Things (IoT) and automation into street lighting systems. The proposed model is a combination of both efficient power generation and smart power consumption. By detecting the presence of people or vehicles, the street lights are made to glow at maximum brightness to minimize energy consumption. Thus, power consumption can be reduced by turning off the lights automatically, when there's no vehicle crossing by. In short, the street lights are controlled based on the traffic density. This paper also proposes the usage of renewable energy sources instead of conventional energy sources. Being environment friendly and a great relief to the problems overcome by excess power consumption, solar street lights are a major benefit for the society.
