Sistema IoT automatizado de monitoramento não invasivo da corrente elétrica de residências utilizando o microcontrolador ESP8266

Abstract

The use of the Internet of Things (IoT) in home automation is extremely important in the pursuit of sustainable development and awareness of energy source depletion. This is because these technologies enable automated monitoring of electrical current, real-time analysis, and data sharing to identify usage patterns and combat resource wastage, contributing to operational efficiency and sustainability in homes. Thus, the aim of this work is to develop a mobile application for monitoring residential electrical current using a non-invasive current sensor and storing the data in a cloud database. This allows users to track acquired electrical current data and compare it with electricity utility bills. In this research, the methodologies and equipment used in its development will be presented, such as Arduino IDE, ThingSpeak, Thunkable, Airtable, the ESP8266 microcontroller, and a non-invasive sensor capable of monitoring alternating electrical current flow. As a result, various data could be obtained through a fully portable, quick, and practical monitoring, aiming for optimization in electrical energy usage, identification of potential issues in electrical systems, and future cost reductions in homes.
