IOT based Smart Street Light System

The aim of IoT Based Smart Street Light System is the conservation of energy by reducing electricity wastage as well as to reduce the manpower. The Saved energy can be utilized in various purposes like residential, commercial etc. This is done by using the LDR sensor. Here the LDR sensor is used ON-OFF the street light based on the ambient intensity level. It is an uncomplicated light/dark activated switch and contains a relay at its output. This switching can be done by a low-cost Wi-Fi module ESP8266 after reading the LDR value. The real time information of the street light (ON/OFF Status) can be accessed from anytime, anywhere through internet. It ensures high reliability and excellent long-term stability. This work is implemented using a programmed NodeMcu board for providing the required intensity of light at various times. The proposed work has achieved a better performance compared to the existing system.
