In this book will learn how to make our own IoT Based Electricity Energy Meter using ESP32 & Monitoring data. We enabled smart energy meter which is capable of two-way communication and can display various parameters through its in-built display as well as through an web based Head-end-System application software. The meter measures energy usage, current, voltage, power and provides the bill amount in real-time. This meter eliminates the need for manual checks for collecting meter data and generating electricity bills. The IoT enabled meter can transmit this data to multiple devices at once, allowing various entities such as consumers, linemen, and the electricity distributors to view the required meter data.
