Abstract : The IoT-Based Single Phase Smart Energy Meter is developed for real-time monitoring and control of residential electrical energy usage. The proposed system employs an ESP32 microcontroller along with sensing modules to measure important electrical parameters including voltage, current, power, and energy consumption.The collected information is displayed on an LCD screen and can also be accessed remotely through Wi-Fi and GSM communication. The smart meter has some useful features such as real time monitoring, overloaded protection, prepaid billing, SMS alerts and remote load control. If there are abnormal conditions like over voltage, under voltage, overload or insufficient prepaid balance, the relay and contactor mechanism will automatically disconnect the power supply. The system also includes a wireless dashboard for simple monitoring and control. This project is a low cost, user-friendly, accurate and suitable for modern residential energy management systems. Users can reduce electricity waste, improve safety and better manage energy consumption.

Keywords : ESP32, IoT, GSM, Real-Time Monitoring, Smart Energy Meter, Energy Management.
