Design and Implementation of Automatic Street Light Controller for Energy Optimization Using FPGA

Abstract: The street lightning consume huge amount of electric power. And the cost per unit is expensive also we have limited resources for power generation so it is always better to depend on renewable sources. Therefore the goal of the present study is to save energy in Street lighting. In the existing system, power consumption takes place due to continuous lighting throughout the night by street lights. Automatic Street Light Control System is not only easiest but also the powerful technique. It releases the manual work at most up to 100% Hence an idea is implement such system which dynamically switch ON and OFF light depending upon traffic and light intensity.. Therefore, maximum power will be saved. The proposed idea was implemented by FPGA and IR sensor.
