IoT - Based Load Management System - An Effective Measure to Save Energy

DOI:10.34047/MMR.2025.12209

Abstract

With the increasing demand for electrical power, preventing overload conditions is critical to ensuring safety and efficiency. This paper presents an IoT-based mains power cut system that monitors power consumption using an ACS712- 30A  current sensor and automatically disconnects loads when a predefined threshold (135W) is exceeded. The system employs an ESP32 microcontroller, a 4-channel relay, and a WebSocket server for real-time control and monitoring. Users can manually or automatically manage loads through a web-based user interface, integrated with ThingSpeak for data visualization. Experimental results demonstrate the effectiveness of the system in preventing overload situations.
