The five criteria of being explicit, quantifiable, realistic, relevant, and time-based are collectively referred to as "smart." IOT refers to the vast and expanding collection of digital gadgets, estimated to be in the billions today, that connect to networks that may have worldwide reach. People are becoming more drawn to the phrase "smart" as the world expands a little faster. Since India's economy is among the fastest-growing in the world, we are applying smart techniques, namely a smart street light system. Even in situations where power is available, the manual streetlight system operates at maximum intensity from dusk till dawn. The energy that is saved can be used for a variety of things, including commercial and residential. The LDR sensor is used to accomplish this. We have the ability to turn a light on or off based on its intensity. The primary supply of electricity for the system is converted via a relay. It is imperative for any city to have a street lighting system. We are utilising an IOT module for the project in order to conserve energy. Everything is becoming more automated as a result of the massive changes taking place in the world. Based on precise, real-time field data, this device makes intelligent decisions and manages itself intelligently.
