PROJETO E DESENVOLVIMENTO DE UM MEDIDOR DIGITAL DE ENERGIA ELÉTRICA MONOFÁSICO PARA APLICAÇÕES RESIDENCIAIS.

Tracking the energy consumption of a residence is a procedure that helps to reduce the energy costs. Even if there are, currently, technological ways of measuring consumption data, which includes automation concepts, it uses techniques that are as effective as those used in smart meters. This paper describes and implements a single-phase digital meter for residential applications. Here, this device is employed as an important tool for the consumption monitoring and for the verification of the effectiveness of adopted energy efficiency practices. For that, it was used voltage and current electronic sensors, a PIC microcontroller, which is responsible for calculate, store and communicate, by means of a Bluetooth module, the electrical measures to a software and an app, which constitutes the system interface. The measures achieved by the prototype was verified with commercial measuring instruments and energy consumption data of a residence was collected and compared with those supplied by the local power utility. Finally, it was proved that the system performed the data storage and sent it to the software allowing further analysis using graphs, which helps in effective energy efficiency actions.
