Implementação e análise de desempenho de um sistema de transmissão de dados a longas distâncias utilizando tecnologia LoRa

Abstract

The implementation of remote environmental monitoring projects, subsidized by low-cost transmission components is a significant challenge, especially in peripheral regions without mobile phone coverage, limited energy availability and difficult access for data collection and equipment maintenance, a typical situation to vast regions of the Brazilian territory. Thus, this work proposes the implementation and validation of a data collection and transmission system in rays up to about 5 km via LoRa. The prototype developed in this work can collect and store data, send it via LoRa radio frequency and connect to the internet via Wi-Fi. The functionality of the low-cost hardware components was programmed in open code that can be selected for the most different types of sensors or applications. Interaction tests with sensors, data transmission and transmission range tests were carried out in an urban region and in a rural region. In the tests performed, the prototype results of satisfactory performance consistent with a reach capacity announced by the manufacturer, reaching distances of 3 km in urban regions and 4 km in rural regions.
