The project aims to design an IoT-Based Smart Energy Monitoring and Control System using Arduino UNO. The proposed system is designed to monitor electrical energy consumption and reduce energy wastage through real-time monitoring and remote load control. In this project, an energy meter is connected to an optocoupler, which detects the blinking LED pulses of the energy meter and sends interrupt signals to the Arduino UNO. The Arduino processes the received pulses to calculate energy consumption in kilowatt-hours (kWh). Voltage and current sensing circuits are also used to monitor the input voltage and load current. The measured parameters are displayed on an LCD and transmitted to the Blynk application through the ESP8266 Wi-Fi module. The user can monitor voltage, current and energy consumption remotely through a mobile phone from anywhere with an internet connection. A relay module is interfaced with the Arduino to control the connected electrical load remotely. The relay switches the power supply ON/OFF according to the user's command through the Blynk application. The entire system is programmed using Embedded C language. This system helps users monitor electricity usage, control electrical appliances and minimize unnecessary energy consumption.
