The IoT (Internet of Things) is a booming technology that mainly concentrates on the interconnection of devices or components to one another and the people. As the time being, many of these connections are changing as Device to Device from Human to Device. Finding the faulty street light automatically is become a vital milestone by using this technology. The primary goal of the paper is to provide control and identification of the damaged street light automatically. Street light fault detector system informs to the concerned area electricity board substation when the street light is not functioning. Because of no proper street light, most of the thefts and accidents are happening. To avoid that sensors can be included in the light pole which sends the signal to the substation if the light is not functioning properly. Sensor sends the information like Area, Street, and Pole ID Number to the electricity substation. Lineman can easily identify the location from the substation and necessary measures can be taken immediately. Sensors added to identify whether the problem is with the solar light panel/ bulb or any difficulty in electricity distribution system. This approach helps for the lineman to work and fix it.
