IOT Based Smart Energy Meter Using ESP 32

Abstract

This paper presents the IOT based smart energy meter to track the energy consumption automatically of the residential load. This meter is capable of sending the consumptions to the consumer as well as an electricity supplier. The readings are taken automatically by using the HLW8012 sensor. Then a predefined set of programs calculates the total bill of energy consumed over the selected interval using the ESP32 microcontroller. The bill is updated in the smartphone by employing a network of Internet of Things. This system eliminates the involvement of the operator for manual methods of taking the meter reading and updating the server for bills. The user can check the number of units consumed by the load at any time using the smartphone. In the future, this idea can be implemented for prepaid metering, which will eventually increase the revenue of the electricity distribution company. We are using ESP32 because of the inbuilt Wi-Fi and Bluetooth facility available in this microcontroller IoT is the combination of collect and exchange data from electronic hardware to the cloud platform and share with the software linked. The platform of the virtual android app is used. Which reflect all the value of Voltage, Current, Power, and unit consumed on the mobile screen.
