Abstract: The Smart Energy Meter is an IoT-based system that tracks and controls electricity use in real time. This project features a Wi-Fi enabled microcontroller (ESP32) to measure electrical parameters like voltage, current, power, and energy consumption. The collected data is sent to the mobile app Blynk, allowing users to check their electricity usage from anywhere. A notification system uses Telegram Bot to inform the user when power consumption goes over a set limit. A relay module is included to automatically cut off the power supply, helping to prevent overload or excessive energy use. This system enables users to manage electricity consumption effectively and cut down on energy waste. The proposed system is low-cost, easy to use, and suitable for homes and small industrial settings. It promotes better energy management through IoT technology.
