Intelligent Street Lighting for Smart Cities

Abstract

Intelligent lighting is designed to optimize the energy consumption for street lighting. The project aims to reduce energy consumption through designing a Smart lighting control system using a microcontroller. Lighting alone accounts for approximately 20% of the global electricity consumption. In the current situation, public lightings are usually turned on before the local sunset and turned off after the local sunrise where visibility is sufficient. Sensory network incorporating infrared sensor, temperature sensor, light sensors are used for real time vehicular detection and ambient light monitoring. A programmable displays, alert system and a real time clock dimming scheduling, notification and measurements are implemented. The microcontroller acts as a microcomputer to govern the operations of the Intelligent street Lighting system. Evaluation shows that through combining different methodology it allows more energy and cost saving in street lighting.
