Abstract

Currently street lights are set to turn on when it gets dark and switch off when it is bright. This is a massive waste of energy worldwide because it is a necessary national service, yet the current execution could be more efficient. This project aims to build a street light control system that will reduce electricity usage. This project proposes a smart street lighting system that uses Zigbee wireless communication and Arduino microcontrollers on each side of Master unit and Slave unit. The system is also equipped with light-sensing module (Light Dependent Resistor) to detect ambient light levels. The system will be active when ambient light falls below certain threshold and stay on sleep mode if ambient lights still high. In this project, the brightness of the lighting is regulated depending on the traffic flow or street activity to reduce power consumption. A sets of motion sensor (Passive Infrared) is used to sense surrounding activity. The lamps fade depending on the pace of detected item motion, such as walkers, bicycles, and autos. The level of light intensity increases as the speed of the moving object increases. The Master unit will transmit the sensors data it collected to the Slave unit via Zigbee wireless transmission. The use of Zigbee wireless communication and Arduino microcontroller allows for a cost-effective and easily scalable solution for implementing smart street lighting. The result and analysis of this project show a smart street lighting system can improve energy efficiency by controlling the brightness of the lights based on the ambient light and the presence of pedestrians and vehicles.
