Design of Raspberry Pi Web-based Energy Monitoring System for Residential Electricity Consumption

Abstract

The application of communication and information technology for monitoring household and building activities is one of the exciting topics in future smart city development research. This paper presents the design of electrical energy monitoring using the PZEM-004T energy sensor and Raspberry Pi 4 as a web server. The system designed for measuring current, voltage, power, and energy and send it to a database as the purpose for display on infographics web pages in real-time. The web pages interface has a responsive design, so the stored data in the database can access on both desktop and mobile phone for flexibility. Based on the results for various loading, it can be concluded that the design of the electrical energy monitoring device is working well with an average error of less than 2%. The user interface also shows the real-time electrical parameter on both desktop and mobile phone.
