72. Integration of Multiple Energy Sources for Hybrid Smart Street Light System

Consumption of electricity by street light is massive. This is due to the conventional control systems that are used which require high range of power. It is not good considering the importance of energy conservation nowadays. Smart and green lighting systems are essential for resolving these problems primarily due to the start of the concepts of smart cities. This paper therefore focuses on the project to design a smart and also green street lightening systems and utilization of renewable energy sources along with new concept of utilization of mobile radiation effectively. The system proposed, comprises of strong ideas and concepts that can control efficiently most of the operations of street lights derived from natural energy sources like the sunlight, wind energy and motion trace by micro controllers, with the support of RF wireless communication. Two conditions are needed to be completed to switch ON the lights. Low levels of intensity of light are detected by LDR sensor. PIR motion sensors are used to detect object present in the street. Without it, the street light will be in OFF condition. So by implementation of SSLS, the consumption of street light can be decreased. The level of carbon dioxide is also reduced due to the use of renewable energy sources. This causes the light to get ON before any vehicle or any pedestrian enters. Also, bright of street light is reduced whenever there is some movement.
