ABSTRACT
The aim of this project is to reduce the power consumption as well as maintenance by providing the Photo sensor that switches the light on and off automatically. The main feature of the Photo sensor is it’s a light dependent resistor. A small hardware model, which is as real as real world application, is built in this project. As the light falls off these sensors switch on the street light and vice-versa.
