DESIGN AND IMPLEMENTATION OF REAL-TIME CURRENT MONITORING USING IoT-BASED AMMETER

Abstract

This paper presents the design, implementation, and evaluation of an Internet of Things (IoT) enabled ammeter system for real-time electrical current monitoring and remote data visualization. The system integrates an ACS712 Hall Effect current sensor with an ESP8266 NodeMCU microcontroller to measure, process, and wirelessly transmit current data to the ThingSpeak cloud platform for remote accessibility. The implementation demonstrates successful measurement of current ranging from 0-30A with an average accuracy of ±1.7%, providing a cost-effective solution for energy monitoring applications. Experimental validation shows reliable Wi-Fi connectivity with 98.5% data upload success rate, real-time data transmission capabilities, and accessible remote monitoring through web-based interfaces. The system architecture enables continuous automated monitoring, historical data logging, and integration potential with broader energy management systems. Testing was conducted using calibrated resistive loads with results indicating acceptable performance for residential and small commercial applications. This work contributes to the growing field of IoT-enabled measurement devices and demonstrates the feasibility of creating intelligent monitoring systems using readily available components. The system provides significant advantages over traditional ammeters including remote monitoring capability, automated data logging, historical trend analysis, and cloud-based accessibility from any internet-connected device.
