Design and Implementation of IoT based Energy Efficient Smart Metering System for Domestic Applications

The aim of this paper is to develop a new energy meter which can communicate with our phones so customers can know the units consumed time-to-time, bill amount need to pay and also gives warning if the energy consumed per month crossed our predetermined value. This can simply call a smart energy meter and to develop this we need a ESP32 microcontroller, sensors, Wi-Fi module with internet connection to communicate with the phone and Blynk platform to monitor units consumed and push warnings in mobile. This can simply be termed as Internet of Things (IoT). This smart energy meter also helps the electricity department to initiate prepaid recharges for the no of energy units to be used and can also initiate auto cut off power supply to the home when there are no units left in the account and the customer should recharge again to get supply back to home. This can make customers more control on their consumption and the energy can be saved and the global environment is saved.
