Desarrollo de plataforma IoT para monitoreo inteligente de potencia electrica utilizando ESP32

Abstract

In this project, a power meter is made using the ESP32 microcontroller programmed in Arduino IDE and a SCT-013 current sensor. A conditioning circuit for reading voltage and current and a phase lock circuit (PLL) are developed. The two cores of the ESP32 are used, one for capturing and processing input signals and the other for data transmission. A Wi-Fi connection is implemented to send Power data to a server. To do this, the HTTP protocol is used and the data is sent in JSON format, which with an IoT (Internet of Things) application allows the sending and receiving of data, facilitating communication with other devices and cloud servers; where a web page is designed that receives the processed information from the server, storing it in a database. The resulting instrument is easy to install and low cost and indicates reliable power measurements. This project is carried out with the support of the LIFAE research group of the Francisco José de Caldas District University.
