A large number of street lights present around the world which consume enormous amounts of electrical energy. As it is a huge system, it is very difficult to monitor and control them manually. It is important to develop a smart system that can monitor and control the lights as well as provide communication to the user. This communication is established using IoT. This system monitors the status of every street light (ON/OFF state) by observing the power consumption of light. As the usage of street light is required only during the night, the system automatically turns ON the light at 6 pm and turns it OFF at 6 am. This conserves energy consumption by optimizing the usage period. When a fault occurs in the street light, this system disconnects the street light from the supply and an indication is sent to the User. Using this information, the User can rectify the fault and turn ON the light. This increases the reliability and maintainability of the street light. A portal for real-time monitoring of voltage across light, current through the light, the power consumed by the light and fault status is established using the Thingspeak IoT platform. This real-time information can be accessed from anywhere around the world at any time using the Internet. © 2020, World Academy of Research in Science and Engineering. All rights reserved.
