Automatic Street Light controller Circuit

 

Introduction & Working:

                                    This project name is Automatic street light controller.This controlled by 6Volt spdt relay.This project used to control the house garden lights. These lights activated on Night time and deactivated on the morning time.This project used to coming generation. Because, this generation is very careless in the save electricity. This project controlled the LED or CFL (0 Watt to 200 Watts) and tube lights. This project power supply used 0-6 volt 500 ma Transformer.This project budget is less then or equal to 200 rupees Including Bulb Holder.
