Desenvolvimento de um sistema de telemetria para monitoramento de qualidade de água em rios amazônicos

Abstract

The present work presents the development of a telemetry system for water quality indicators. The purpose is to enable remote, periodic, and self-sustaining monitoring of chemical and biological parameters in Amazonian rivers through precise sensors over long distances. The implementation of the proposed research began with the modeling of a microcontrolled hardware device designed for low energy consumption, featuring energy harvesting, battery backup, LoRa connectivity, and support for reading laboratory water quality measurement sensors. In addition to the envisioned hardware system, the developed firmware was designed to efficiently coordinate sensor activation, peripheral devices, and LoRa radio communication, as well as establish communication via the LoRaWAN protocol with a web application for displaying water quality information. With the implementation of the proposed telemetry device, it is expected to assess the system’s autonomy in remote locations and compare the measurements taken by the device with those recorded by the research group at the LabRios laboratory, located at the Center for Higher Studies in Parintins. This will ultimately test the viability of the developed solution as a valid tool for monitoring river parameters.
