3. SECTION 3: PROJECT DESCRIPTION
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.
