Abstract: Established street lighting systems have certain drawbacks as they are operated manually. If this system is not monitored properly, this may lead to more energy consumption. This system requires proper monitoring and energy management techniques to reduce energy wastage. To diminish this energy wastage, we propose a system which operates automatically and also can be remotely supervised and controlled with virtual switches using GUI. This Wi-Fi enabled system uses ESP32 as both a controller and Wi-Fi module. Here we use low bandwidth, a lightweight protocol like MQ Telemetry Transport protocol for IOT implementation. To reduce cost of the system, all streetlight (Wi-Fi) nodes are connected with a single router using Wi-Fi mesh network. Each node is having ESP32 and various sensors for power measurement & object detection. This system can be controlled automatically based on seasonal data stored in central base station. In streetlight failure condition ESP32 will send a fail signal to base station and base station will intimate maintenance operator through mail. Here base station and each node communicate through cloud. For remotely control and supervision a GUI is developed using HTML and JavaScript.
