The Smart MCB (Miniature Circuit Breaker) project is an IoT-based intelligent protection system designed to enhance electrical safety and enable remote monitoring and control of power systems. This system uses a NodeMCU microcontroller as the core unit, which is powered by a regulated power supply. The NodeMCU is connected to a web-based interface, allowing users to monitor and control the circuit breaker remotely through the internet. In this project, a servo motor is interfaced with the NodeMCU to physically operate the MCB switch. Based on commands received from the web page, the NodeMCU controls the servo motor to turn ON or OFF the MCB. This enables real-time switching and automation without manual intervention. The system can be further enhanced with sensors to detect abnormal conditions such as overcurrent, overvoltage, or short circuits. When such faults are detected, the controller automatically trips the MCB to prevent damage to electrical equipment and ensure user safety. Overall, the Smart MCB system provides a reliable, cost-effective, and user-friendly solution for smart energy management, remote control, and electrical fault protection. It is highly suitable for modern smart homes, industries, and energy-efficient systems.
