Energy monitoring and management have become essential in modern electrical systems due to increasing power demand and the need for efficient utilisation. This paper presents the design and implementation of a smart energy meter using Arduino and ESP8266 for real-time monitoring of electrical parameters and cost estimation. The system measures voltage, current, power, and energy consumption and displays the results on a 16×2 LCD and a mobile application through Wi-Fi communication. The proposed system also incorporates protection mechanisms such as overvoltage and overcurrent protection using a relay module. Additionally, energy theft detection is implemented by comparing main and sub-meter readings. The system is cost-effective, reliable, and suitable for smart grid and home automation applications.
