Desenvolvimento de um sistema de baixo custo para monitoramento remoto do consumo de energia elétrica

Abstract

In order to facilitate the monitoring of electric energy consumption, the present paper presents the development of a low cost system, with mobile device interface, capable of measuring the active power consumed by electric charges and calculat-ing the energy consumed by them. To measure the active power demanded by the load, the system uses the ESP8266 NodeMCU module, connected to an MCP 3909 energy analyzer CI. The information is sent through the WI-FI network to a mobile applica-tion, developed using the Ionic framework. The application interprets the data and show the consumption information for the us-er. An experimental prototype of the system was assembled and tested in laboratory for measurement adjustments and percent error analysis. In this paper, it is detailed the complete development of the hardware and the mobile application, as well as the experiments and results obtained.
