Medidor de consumo de energia elétrica utilizando o microcontrolador ESP

Abstract

Energy efficiency is a crucial aspect in the current context of resource scarcity and environmental concerns, aiming to optimize energy consumption by reducing waste and promoting sustainable use. In this scenario, the electrical energy consumption monitoring system developed with the ESP32 microcontroller and the Peacefair PZEM-004T meter emerges as a viable solution for necessary measurements. The main goal is to provide an efficient tool for real-time energy data measurement and analysis using Bluetooth Low Energy communication. This enables the connection between the ESP32 and the mobile application developed on the Thunkable platform, allowing data visualization on Android and iOS devices. The methodology involved integrating the PZEM-004T with the ESP32 via UART communication. Tests conducted with an 8W LED bulb were validated by comparison with the Atorch S1 meter. Results demonstrated that the system is functional and offers a low-cost, easy-to-implement alternative for monitoring energy consumption in homes and businesses. This approach supports the automation and efficient control of energy, standing out as a practical solution for energy consumption management. Additionally, it promotes awareness of the importance of energy efficiency.
