Desenvolvimento de protótipo de sistema de baixo custo para monitoramento da qualidade da água de Bacias Amazônicas

Abstract

This document presents the project for the development of a low-cost system prototype for monitoring the water quality of Amazon Hydrograhics basins. The scientific study aims to find solutions that can monitor the river water quality,specifically in the Amazon Region, since there is no monitoring system similar to this one, mainly capable of receiving infor mation of water parameters in real time. All the components of the system, the theoretical and practical principles of its operation, the objectives and gains resulting from the project are presented in a structured way. First of all, the theoretical foundation of the technologies used is shown, presenting the sensors that will be used for each determined parameter (temperature, pH, TDS and turbidity), based on the ESP32 LoRa platform for data acquisition, processing and sending, firstly via LoRaWan communication protocol and then via Wi-Fi communication network or via mobile data networks to a monitoring center. These components will be con fined in an acrylic box developed to hold the electronic circuit, in which it will float on the river water due to the use of pool noodles. The pertinent information will be displayed on an IoT platform (Arduino IoT Cloud), which is exclusive software for IoT development. Then, in methods and materials, the stages of project development, materials, equipment and soft ware used are presented. Later, in project implementation, the methodologies used for the study are detailed and how the components must interact to collect the data necessary for the scientific study. The conditions and limitations of the theoretical model and their differences in relation to the real conditions of the natural environment will also be informed. Afterwards, in the results obtained, the data of the project in its full functioning are shown and analyzed. Finally, it is concluded from the data obtained that the proposed solution, applied the improve ments and changes necessary for its functioning in the natural environment, can be tested in real conditions so that it can be used in anothers regions of the world.
