Abstract: This paper aims to present an Intelligent Street Light System which is used to control the intensity of street lights based on motion detection of people and vehicles and to turn on the LED lights only when required. The system provides a cost-effective and an energy efficient solution for street lighting applications. The system operates in two modes, Bright state and Dim State. Passive Infrared (PIR) Sensors are used for motion detection. On detection of motion, the LED Bulbs are put into BRIGHT state, which otherwise remain in DIM state. The change in intensity levels from DIM to BRIGHT and vice-versa is achieved by a dimmer circuit. Detection of motion is also communicated to neighboring street lights, over WiFi, which also then change their state to BRIGHT state. The microcontroller used is ESP8266.
