Solar Powered Led Street Light with Auto Intensity Control

Abstract

All varieties of street lighting use a lot of energy and are essential for ensuring public safety. In order to ensure public safety, keep street lights on and at the right degree of illumination for both pedestrian and vehicular traffic. This will also make energy conservation simpler and more effective. For businesses in charge of street lighting, operational dependability, or maintenance expenditures, any energy use savings therefore pay off handsomely. This project's main goal is to use an Arduino board to regulate the brightness of street lights. As the night goes on, traffic gradually reduces. This project's main goal is to use an Arduino board to regulate the brightness of street lights. As the night goes on, traffic gradually reduces, Traditional HID lights are being replaced with white light emitting diodes in street lighting systems that can be dimmed (LED). Because of their high longevity and minimal energy use, LED lights are the lighting of the future. Due to the ability to change intensity using pulse width modulation, LED lights are swiftly replacing conventional lights. An Arduino board and a rectified power supply are used in this setup. A MOSFET device is used to link a string of LEDs to the Arduino board. To alter the LED light's intensity, one can alter the duty cycle of a DC source. The PWM method is used to give varied intensities at various times of the night using an Arduino board that has been configured. The LDR in this project also enables it to appropriately track the changeover process.
