Desenvolvimento de registrador de pulsos conectado à internet para medidores de energia eletrônicos

Abstract

The present work aims to present the development of a system for getting the load curve and testing the calibration of electronic meters. The system is composed of a connected device on a meter for which it is responsible for the pulse reading and sending the data with Wi-Fi for a cloud database. The device was built using the NodeMCU, a hardware development environment, and a sensor of color and gesture sensor for detecting the pulses. To control the recorder and visualize the data was developed a mobile app. The app displays the real-time load curve and provides tools for estimating the cost of the energy consumed. Based on the above, the system was tested in the laboratory with three electronic meters distinct. To analyze the precision of the calibration test and the getting load curve, was collected too data with others equipment with similar features. Through the tests, was proven the efficiency of the system in collecting relevant data for the consumers using the Kh constant.
