Desenvolvimento de um aplicativo Android para monitoramento do consumo de energia elétrica de uma residência

Abstract

The objective of the project was to develop a prototype for monitoring the consumption of eletrical energy, presenting the values in an Android application, to allow control and enable a conscious consumption of eletrical energy. To that, voltage and current readings were taken at a socket, with eletrical and electronic devices connected. The modules were used: (ZMPT101B), to measure the network voltage; (b) ACS712, to measure the electrical current of the device; and (c) relay, to allow the user to enable or disable the socket through an Android application, developed in programming language Kotlin. To process the data an ESP32 was used, with the data being stored in the Firebase database. The application allowed the presentation of this data in graphic and table format, so that the user could monitor consumption, in addition to presenting total consumption and price in real.
