Design and Implementation of an IoT Based Home Energy Monitoring System

This paper presents “The Design and Implementation of an IoT Based Monitoring System for Home Energy consumption”. The system monitors appliances by providing real-time, energy usage, and other data and has the capability of wireless disconnection and connection of loads. The methodology consists of PZEM-004T meter module for consumption pulse measurement, which the ESP8266EX Microcontroller records. This microcontroller requests updates every second and manages unit consumption and other meter activities. This information is transmitted to the ThingSpeak cloud platform and later visualised with High-chart. The software aspect of this work is in two-fold namely the programming of the microcontroller in C++ to achieve the monitoring functionality of the system and the development of communication command using C++ and HTML. The result of the test carried out shows a range of 1 to 5seconds taken by the system in switching appliances depending on the network mode. The results show that the system is good for monitoring energy consumption in a home especially in dual mode - wireless and offline, as such, it allows users to use energy judiciously by providing real-time consumption data. The prototype of the IoT-based home energy monitoring system worked satisfactorily and it is dependable and efficient for use in homes.
