AUTOMATIC STREET LIGHT WHICH WORKS BASED ON THE VEHICLE MOVEMENT

IR Sensors used on either sides of the road send logic commands for the LEDs at the output to get glowing for a patch ahead.Intensity control is also possible by pulse width modulation based on sensing the movement and density of vehicles.Thus this way of dynamically changing intensity or off to on helps in saving a lot of energy.A programmable microcontroller is engaged to provide different duty cycle for different intensities at different density conditions
