Mobile Based Electronic Home Appliance Remote Control and Power Consumption Monitoring Using Internet of Things

Abstract

Knowing which household electric appliance is consuming how much electricity is sometimes the key issue in managing domestic power consumption. In this paper, design and analysis of a low-cost and easy to implement home electric appliance controlling and energy monitoring system is proposed. The proposed system is built based on Internet of Things (IoT) equipment and protocol. This will enable the user to monitor energy consumption of connected home appliances and control them via a mobile application. The proposed system consists of two major components: IoT hardware and user interface software for that hardware. The first part is, development of an IoT prototype device that would fit inside a traditional switch board. This component contains the controlling hardware for electronic appliances, and a sensor to measure energy consumption. The prototype device has been constructed using Wi-Fi module, opto-isolated relays for communication and stability. The second part is a mobile application through which the user can control and monitor energy consumption for each home appliances. The proposed hardware and software package calculated energy consumption for a household with a reliable accuracy while it was deployed for a month. Keeping users need in mind, real-time data visualization is made available through the mobile app. The app also provides historical data summary and temporal uses comparison as well as cross device power consumption comparison.
