Street Light Energy Saver

Abstract

Street Light Energy Saver, a work that focusses on the pressing issue of energy consumption worldwide, is built with the aim of decreasing the power usage of street lamps during the time with no sunlight when their requirement in certain areas is minimum. The aim is improving the efficiency by decreasing the illumination factor of lights. Roads, especially the one connecting to the residencies, have minimum traffic at night hours, and hence, it is crucial to save upon the excess wastage of energy. It is often observed that most of the roads at isolated places are rarely visited after 12 am. The traffic gets filtered past 10 pm, and only few of vehicles pass through those roads. But the system in place is such that whatsoever the traffic maybe or whatsoever is the hour during the night, the street lights are always switched on. With the increasing connectivity of the road and hence the skyrocketing energy consumption, it has become the need of the hour to preserve upon the precious source of energy. This, thus, can only be achieved through some system in hand which, to some extent, walks on the lines of conservation. The Street Light Energy Saver is one such initiative that envisages to achieve the goals. The work when deployed in places will have street lamps emitting 50% of the light when no vehicles are passing. This would be done by deploying IR sensors in order to sense the traffic on the road, during a provided time of the night. The IR sensors will send the signal to the microcontroller which would decide about illuminating the lights to 100%. As soon as a single vehicle would pass, it would switch to 100% and then back to energy saver mode. This would reduce the energy consumptions by great margins.
