Automação de estação elevatória de água tratada via módulo de rádio de baixo custo

Abstract

In this work, a low cost radio automation system for application in water supply systems is proposed. In the water transport stage, that comes out from the treatment station to the elevated water tank, pumps are used to pressure the water and to transport it for long distances between these two places. The manual drive of this system can cause problems, as the need of human intervention and water waste since there is no level monitoring for the tank. After a research about wireless communication technology, sensors and actuators, a level sensor based in pressure difference and a module based in LoRa technology were selected. The obtained results evidence that the proposed radio automation system provides greater independence from human intervention and provides water level control, avoiding water waste.
