Desenvolvimento de um módulo de comunicação via rede elétrica - PLC.

Abstract

The idea of communication through the power grid has a long history of development. However, despite having interesting features, this technology known as Power-line Communication (PLC), is not well explored on the national scene, especially in home applications, which is undergoing constant advances related to the Internet of Things (IoT). Thus, it is proposed in this work a fully functional hardware module, aimed at the development of applications for IoT, with the ability to communicate over the power grid and to interface with several available communication standards, such as I²C, SPI, UART and USB. For this purpose, this module has a ST7538Q modem, operating in Narrowband and with a transmission rate of 4800bps, in addition to a microcontroller responsible for controlling the use of the PLC modem and managing communication between modules.
