PROJECT DESCRIPTION

The project is designed to detect vehicle movement on highways and then to switch on only a block of street lights ahead of it (vehicle), and then to switch off the trailing lights to save energy .Traditionally during night, all the lights on the highway remain switched on for better visibility to the running vehicles. But lots of energy is wasted when there is no vehicular movement. This system also has inbuilt day/night sensing techniques.

This proposed system provides a solution for energy saving. This is achieved by sensing an approaching vehicle and then switching on a block of street lights ahead of the vehicle. As the vehicle passes by, the trailing lights gets switched off automatically.

Thus, the system saves a lot of energy. If there are no vehicles on the highway, then all the lights remain off. However, there is another mode of operation where instead of keeping switching off the lights completely, they remain on with 10% of the maximum intensity of the light. As the vehicle approaches, the same block of street lights switch to 100% intensity and then as the vehicle passes by, the trailing lights revert back to 10% intensity again.

High intensity discharge lamp (HID) presently used for urban street light are based on the principle of gas discharge, thus, the intensity is not controllable by any voltage reduction. White Light Emitting Diode (LED) based lamps are soon replacing the HID lamps in street light.  Intensity control is also possible by Pulse Width Modulation (PWM) generated by the microcontroller.

Sensors used on either side of the road sense vehicle movement and send logic commands to the microcontroller to switch on or off the LEDs. Thus, this the way of dynamically changing intensity or  ON/OFF helps in saving a lot of energy. The project uses an 8051 series microcontroller. An LDR is used to sense the day or night conditions that enables the power supply to street light only in the night time.

Furthermore, the project can be enhanced by using appropriate sensors for detecting the failed street lights and then sending an SMS to the control department via GSM modem for appropriate action.
