Abstract
In this paper, a PIC16f877a microcontroller is used to build and run an IoT-enabled energy meter. The system architecture proposed eliminates the need for manual electrical maintenance. The Buyer is responsible for the cost of the electricity consumed. If the buyer does not pay on time, a remote server may turn off the power. Users can find out how much energy their device uses by going to a website and entering their device's IP address. When the energy meter is tampered with, the attached theft detection unit sends a signal to the corporate side via a GSM modem. This signal will be displayed on a corporate terminal. The Wi-Fi module handles the IoT task of transmitting energy meter readings via an IP address to a public website. A PIC16f877a microcontroller, a MAX232, an LCD display, a theft alarm, and an ESP8266 Wi-Fi module are all part of this hardware interface circuit. The Wi-Fi module handles the IoT task of transmitting energy meter readings via an IP address to a public website.
