IOT-Based Smart MCB Control with Real-time Temperature Monitoring

This study explores the development of an IoT-enabled home automation system that integrates a smart circuit breaker (MCB) and an adaptive temperature-based fan control mechanism. The proposed system enhances electrical safety by allowing users to operate the MCB both manually and automatically, ensuring greater control over power distribution. Additionally, the system optimizes energy consumption and enhances occupant comfort by dynamically adjusting fan speed in response to real-time temperature fluctuations. When the ambient temperature rises beyond a predefined threshold, the system increases the fan speed, while a temperature drops results in a proportional reduction in speed. Smart sensors continuously monitor temperature and power loads, transmitting data to a microcontroller for real-time processing and automated decision-making. Cloud connectivity further facilitates remote access and control via a user-friendly mobile application. This research underscores the potential of IoT in modernizing household electrical systems, fostering intelligent energy management, improved safety, and seamless automation for enhanced user convenience.
