PIC Microcontroller based Street Light that Glows on Detecting Vehicle Movement

The main goal of this project is to detect a vehicle movement on highways and switch ON only a bunch of street lights ahead of it, and then to switch off the lights when the vehicle passes away from the lights to conserve energy. During the night time, all the lights on the highway remain ON for the vehicles, but lots of energy is wasted when there is no vehicle movement.

Street Light that Glows on Detecting Vehicle Movement
Street Light that Glows on Detecting Vehicle Movement

This project gives a solution that helps conserve energy which is achieved by using sensors that sense an approaching vehicle on the highways and then prompt a bunch of street lights ahead of the vehicle to switch on. As the vehicle passes by the street lights, the system automatically switches off the lights.

Presently, HID lamps are used in urban street systems; HID lamps work on the principle of gas discharge. Thus, the intensity is not controllable by any voltage reduction. In the future, white LED-based lamps will be replaced by HID lamps in the street lighting systems. Light intensity is also possible by PWM (pulse width modulation) which is generated by the PIC microcontroller.

Sensors that sense vehicles’ movement is placed on either side of the road to send signals to the microcontroller so as to switch on/off the LEDs. Thus, this project helps to conserve a lot of energy. Furthermore, this project can be developed by using suitable sensors not only to detect the failed street lights on the highway but also to send SMSs to the control department through a GSM modem for corrective action.

PIC Microcontroller based Auto Intensity Control of Street Lights

This project is used to control the auto intensity of the street lights using a PIC microcontroller. This proposed system uses light-emitting diodes in place of HID lamps in the street lighting system to conserve energy. PIC microcontroller is used to control the intensity of light by developing PWM signals that drive a MOSFET to switch the LEDs accordingly to the desired operation.

The intensity of street lights is kept high during peak hours; as the traffic on the roads tends to decrease slowly in the late-night hours, the intensity also decreases gradually until morning. Finally, it completely shuts down in morning 6 and again resumes at 6 pm in the evening. Furthermore, this project can be developed by integrating it with the solar panel, which helps convert the solar intensity into corresponding energy which is used to feed the highway lights.
