Web-Based Energy Monitoring System and Tariff Calculation for Residential Electricity Consumption

Abstract

The goal of this project is to develop and deploy a web-based energy monitoring system for residential electricity consumption using Internet of Things (IoT) technology and various hardware elements, including a Raspberry Pi Pico, LCD display, current coil, relay energy meter PZEM004T, ESP8226, and RFID. The planned system will enable households to track their energy usage in real-time via a web-based interface, giving them insights into their energy usage habits and assisting them in finding ways to lower their electricity bills. The device will also compute the electricity rate depending on energy consumption and display it on the LCD screen. The hardware elements will cooperate to track and measure energy use, with the current coil identifying the power theft and give alert to the user via web server or via mobile application. An RFID tag and reader will be used for the purpose of prepaying option, that will display the amount which has been paid by the user. This web-based energy monitoring system will give households an affordable and practical tool to track their energy usage, prepaid amount, lower their electricity bills, and contribute to a more sustainable future.
