Implementação de um dispositivo para Rede de sensores sem fio LoRa ® utilizando energia solar

Abstract

Wireless Sensor Networks are increasingly being used in various types of systems focused on monitoring. Among the communication protocols used by these systems, LoRa ® has gained prominence because it supports transmission over much longer distances than the others, requiring little energy. Use renewable energy sources as energy solar, has also been a trend, with the main purpose of not harming the environment as well as making the system application cheaper in the long run. The present thesis proposes the development of a device to operate in a wireless sensors network using LoRa ® protocol, as well as solar energy as a source of system power. The device should have some sensors in such a way that the system be focused on agriculture applications, improving the process. The results include a detailed process for selecting each device component as well as the behavior of each sensor over a 24 hours of reading and transmissing period. In addition, the device main features are shown as configurations of microcontroller peripherals and modules.
