IoT Based Energy Monitoring & Automatic Billing System

IoT Based Energy Monitoring & Automatic Billing System

The IoT Based Energy Monitoring & Automatic Billing System is a smart electrical energy management solution designed to monitor real-time power consumption and automatically calculate electricity billing using IoT technology. The system enables users to track voltage, current, power, and energy usage remotely through a mobile application, improving transparency and energy efficiency.

The project is presented on a clean white base with a pure white background, giving it a professional and industry-ready appearance. A compact ENGINEER’S BUTTY LAB BD logo is positioned at the top-left corner, scaled to be three times smaller than the main hardware components to maintain branding without visual distraction.

System Overview

This system continuously measures electrical parameters from connected loads and sends the data to a cloud platform via an IoT-enabled microcontroller. Users can monitor live energy usage and billing information using a smartphone application, making it ideal for smart homes, offices, and industrial environments.

Key Components Visible

• IoT Microcontroller (ESP-based) – Handles data processing and cloud communication

• Energy Measurement Sensor Module – Measures voltage, current, power, and energy

• Relay Modules – Control connected electrical loads remotely

• LCD Display (16×2) – Displays real-time electrical parameters

• AC Load Bulbs – Demonstrate real-time power consumption

• Mobile Application Interface – Shows live energy data and billing values

All components are neatly arranged, properly wired, and clearly visible, ensuring ease of understanding for academic evaluation and client demonstration.

Working Principle

The energy sensor continuously measures voltage and current supplied to the load. The microcontroller calculates power and energy consumption, then uploads the data to a cloud-based IoT platform. The mobile application displays real-time values such as voltage, current, power, and total energy used, along with automatically calculated billing information. Loads can also be controlled remotely using the app.
