Desenvolvimento e avaliação de um medidor inteligente via ESP8266 NodeMCU V3 e módulo PZEM-004T

Abstract

The rational use of electricity in Brazil and in the world is essential to increase accessibility, energy security in nations, sustainability and technological development. In this universe, IoT technologies (i.e., Internet of Things) have emerged to vastly improve the user experience and communication between people and processes. Thus, smart meters stand out as a tool to energy monitor, in real time, and remotely, energy consumption. In the current context, as a standard practice for rationalizing the use of energy, concessionaires and final consumers have been replacing low-performance equipment with high-performance equipment. However, with regard to waste levels, still very little is done. In this scenario, therefore, much research and development has been carried out for the use of advanced remote monitoring technologies as an alternative to mitigate this waste. It is worth mentioning, however, that at the residential level there are still no well-established technologies to simultaneously meet operational, financial and cyber-security requirements. This work proposes to use a commercial microcontroller (i.e., ESP8266), of low cost, for energy monitoring and to develop an Android application to communicate real-time data from the client to the server on a Cloud platform via MQTT protocol.
