IoT-Based Circuit Breaker Monitoring

Abstract

The growing interest in Internet of Things (IoT) applications has paved the way for advanced solutions in electrical infrastructure monitoring. This paper presents an IoT-based circuit breaker monitoring system using the ESP32 microcontroller, designed to enhance the safety and efficiency of power distribution networks. The system integrates ZMPT101B AC voltage and ZMCT103C current sensors to track real-time electrical parameters such as voltage, current, and breaker status. Connected to the Blynk IoT platform via Wi-Fi, it enables users to monitor and control the system remotely through a mobile application. An automatic cutoff mechanism is triggered by excessive current, while manual control is available via the application. Additionally, a relay provides protection by disconnecting circuits in dangerous situations. Continuous real-time monitoring and cloud-based analytics help predict potential faults, reduce downtime, and automate responses to abnormal conditions, creating a comprehensive solution for efficient and secure circuit breaker management.
