Auto-Intensity Regulation of Streetlights using Arduino

Street lights are essential but costly, therefore the need of the hour is to optimize and bring about innovation in the sphere of street-lighting. Untimely switching on and off, and incessant glowing throughout the day without intensity regulation contribute to tremendous energy wastage. Also, manual control is tiring and outdated in this day and age of automation. It is of dire need to revolutionize the ways and means through which these lights are operated. The ultimate goal is to save energy, long term costs, and manpower along with attaining management of time and a systematic cycle of operation. In this paper, a befitting model that makes use of Arduino board is proposed which addresses these concerns. It is the brainpower of the entire setup. Light dependent resistor (LDR) and infrared (IR) sensors are some of the major components used in smart street lighting. IR sensor detects movement and LDR powers the street lights only after evening. Another vital component is the Real time clock (RTC) which gives the real time to circuit. On implementing the model, it is clear that the use of Arduino Uno along with LDR, IR sensor and RTC achieve the aim of intensity regulation on the basis of need and automation of the process. Introduction, working, calculations and analysis along with related works have been discussed. Conclusions are made in the end.
