Review on IOT Based Smart Energy Management System

The aim of the project is to save the energy or power, used in public places like waiting hall, libraries, Class rooms etc. When people not present in the room then the system automatically switched off all the appliances. Whenever any person or group of persons enter in the room then the Counter based on IR Sensor sends signal to Microcontroller, then microcontroller check the light intensity available in that room. Light sensor is used to detect the light intensity of the room. Depending up on the light intensity it decides how many lights need to switch ON. Similarly, it checks the room temperature also. Temperature sensor used here to measure the current room temperature. If room temperature is high and someone present in the room then only fan gets switched on otherwise it remains off, and when all the persons left the room the control unit automatically switched off the devices.
