Prototype of a single-phase and two-phase electric power meter for residential consumption monitoring using an ESP32

Abstract

This article describes a prototype of an electric power meter in the monophasic and biphasic levels. Its purpose is to monitor residential consumption, based on a low-cost microcontroller, which through sensors can obtain the current and voltage values to find the variants of power and cost. The communication is established through a web server that is developed in the C language in conjunction with the Arduino libraries.
