Design and Implementation of an IoT-Based Smart Energy Meter for Real-Time Monitoring and Automated Billing

Abstract: With the growing demand for efficient power management, this project introduces an IoT-Based Smart Energy Meter that enables real-time monitoring, automated billing, and remote accessibility. The proposed system continuously measures electrical parameters such as voltage and current using precision sensors interfaced with an ESP32 microcontroller. The microcontroller computes power consumption and transmits the data wirelessly to an IoT cloud platform, allowing users to visualize their energy usage through a mobile or web application. This eliminates manual meter reading, reduces human error, and ensures accurate and transparent billing. The system is also equipped with alert notifications that inform users of excessive power consumption, helping to encourage energy-efficient behavior. The integration of IoT technology, sensor data acquisition, and wireless communication provides a scalable and intelligent framework suitable for both residential and industrial applications. Overall, the project offers a practical approach to modernizing energy metering systems and supports the transition toward smarter and more sustainable power management solutions..
