Desenvolvimento de um sistema genérico de aquisição e transmissão de dados sem fio

Abstract

Technological evolution has driven the search for efficient and low energy consumption solutions in several areas. In this context, the development of data acquisition and transmission systems using low-power protocols such as zigbee, LoRaWAN and bluetooth has proven to be an area of great relevance in the world of the internet of things. This work proposes the development of a generic system for acquisition and transmission of essential variables, capable of acquiring analogue/digital data and transmitting them accurately using a system that uses low energy consumption components. With this, a development of a generic and adaptable embedded system capable of acquiring and transmitting data is presented. The hardware of this device was developed around the ATSAMR21G17A-MF microcontroller, which incorporates the AT86RF233 radio. This radio is responsible for transmitting data through the 802.15.4 protocol, used for Zigbee communication. As for the system firmware, it was programmed in C/C++ language on the microchip studio platform with the aim of integrating data acquisition and transmission.
