Automatic street Lights

Here is our new Automatic Street Light Control System for students and hobbyists.

• It is a simple and powerful concept, which uses transistor as a switch to switch ON and OFF the street light system automatically.
• It automatically switches ON lights when the sunlight goes below the visible region of our eyes. (e.g in evening after Sunset).
• It automatically switches OFF lights when Sunlight falls on LDR. (e.g in morning after Sunrise) LDR (Light Dependent Resistor) is a type of resistor, whose resistance changes according to the intensity of the light falling on it.
