REMOTE ACCESS LARGE ELECTRICAL METER

Abstract

The high cost of electricity due to generation, distribution and fees brings a single income value for several families, requiring a greater amount of information on the electricity consumption of each appliance, as well as an entire residence. There is currently no market for apparatus, recording and analysis of electrical quantities. The objective of the present work is to create a prototype for the registration and monitoring of electrical quantities, aimed at implantation in the residential area. The project is based on a PZEM-004T v3 module with a capacity of up to 100A, using as a non-invasive current sensor and an ESPDUINO32 development board to retrieve data from the sensors that will be sent to the server via the Internet, and can be accessed by computers or Smartphones. The developed energy monitoring system can record voltage, current, active, reactive, apparent power, power factor and accumulated energy consumption. After the prototype was built, several measures were taken to prove the feasibility of its use, but it was not possible to calculate the percentage error of energy consumed due to the lack of adequate equipment. The tests were intended to show the possible use of the device as an instrument of use.
