Design of Automatic Intensity Controller of Street Light and it’s Energy Efficiency

Abstract: The design of the project focuses on intensity control of the street light that saves power consumption. The concept is to control the intensity of LED bulbs used through the use of Arduino and RTC DS3231 module. The Arduino controls the light intensity of bulbs on three divided sections of time. That is from 6 pm- 10 pm with full intensity (100%), 10 pm – 12 am with 50% reduction and 12 am – 6 am with reduction to 25%. And this proposed system can bring better result compared to existing system by reducing the unnecessary power consumption in the lighting system.
