Automatic street light control system using wireless sensor networks

Energy consumption due to the street lights needs proper monitoring and control to reduce wastage of power. Conventional street light systems suffer from certain drawbacks as they are manually controlled and are powered through the electrical board power station. This may lead to more power consumption if not monitored properly. In this paper, an automatic street light control system is implemented based on wireless sensor networks (WSN). The street lamp post forms the WSN node. It uses an Arduino Uno board and various sensors to detect traffic on the road. A Raspberry Pi3 computer is used as a web server at the central base station to monitor the status of the street lights. The lights are turned on based on the sensor signals only during nighttime and when traffic is present. A webpage is developed using HTML and PHP language for uploading the sensor data and web control of the street lights. Solar cells are used at each node to power on the street lights.
