IOT-Based Smart Circuit Breaker with Smart Monitoring

The rapid growth of electrical loads and the increasing complexity of power distribution systems demand advanced protection and monitoring solutions. Conventional circuit breakers provide basic protection against overcurrent and short circuits but lack real-time monitoring, remote control, and intelligent decision-making capabilities. This paper presents the design and implementation of an Internet of Things (IoT)-based smart circuit breaker with smart monitoring features. The proposed system integrates current, voltage, and temperature sensors with a microcontroller and cloud platform to enable real-time monitoring, fault detection, and remote operation. Parameters such as load current, power consumption, breaker status, and fault conditions are continuously monitored and transmitted to a cloud server for analysis and visualization. In the event of abnormal conditions, the system automatically trips the circuit breaker and notifies the user through a mobile or web application. The proposed solution enhances electrical safety, improves energy management, reduces maintenance efforts, and supports predictive fault diagnosis, making it suitable for residential, commercial, and industrial applications.
