Abstract

This study presents the design and implementation of an interactive, user-friendly electronic meter for energy consumption measurement. The proposed system serves as an educational tool for teaching electrical installations, offering a practical and hands-on learning experience. The primary objective is to develop an interactive meter tailored for residential use, capable of providing real-time feedback on energy consumption. Its deployment in educational institutions enhances the comprehension of technical concepts, while also proving beneficial in community outreach workshops focused on residential electrical systems. The system consists of a battery-powered setup featuring an ESP32 module for voltage and current data acquisition, an SPI-connected LCD screen for local data visualization, and a WiFi module for real-time data transmission to a cloud-based database. Designed to be reproducible, cost-effective, and open source, the system represents an accessible and versatile solution for energy monitoring applications. Validation tests were conducted over five months in both laboratory and residential environments. The results demonstrated high measurement accuracy, with error margins below 5% for voltage, current, energy consumption, and estimated costs. These findings confirm that the developed interactive energy meter is a reliable and effective tool for monitoring residential energy usage while fostering educational and community-based learning experiences.
