ESP32 Microcontroller Based Smart Power Meter System Design and Implementation

Abstract

Every house and workplaces should install electricity energy meter to evaluate the electricity consumption. Finally of consistently, a large number of us get stressed over the high power bill and it is need to check the energy meter once in a while. In this work a smart electricity energy meter using ESP32 microcontroller which monitor energy through the PZEM-004T at any time and send to the office. Where this PZEM-004T is used for voltage and current measurements. Then the records will send to the office and store in the SQL database and also web page which is used specific IP. The results have been generated using MYSQL and the curves of the values with the time are also plotted using Microsoft Excel 2010.
