A Sensor-Less and Energy Efficient Street Light Control System

Dheeraj sharma

Work in this paper is directed towards the design of a cost effective and energy efficient Street light control system. The main idea is to provide an alternative to LDR and Hardware timer based street light control systems which have reliability and efficiency related issues. Light dependent resistors are prone to signal variations due to factors such as presence of dust, humidity etc. and therefore their outputs cannot always be relied. Hardware timer based controls have no such issues but due to the improper and untimely manual changeovers of time settings of the controls, they are not quite efficient. Some recent research work has been done on controls employing LASER gates to detect traffic in vicinity which switch on the lights only when there is presence of vehicles but such types require huge infrastructure for installing Laser transmitters and receivers at a height of two feet near each street lamp post which is not feasible keeping in mind the scope of the paper.
