Résumé:
The increase in water demand occurs with population growth, but this resource is finite. In the Northeast of Brazil, water scarcity and long periods of drought make an efficient management of water necessary. The objective of this research was to develop a low-cost system for automated monitoring of the volume of water in a reservoir, to control consumption and manage the available water resource. The sequence of steps to achieve the objective was the making of a hardware device to measure the volume of water, the implementation of a software to monitor the data, the installation of the device in one of the water reservoirs of the Federal University of Campina Grande - Campus Sede, and finally the analysis of the data obtained by the system. This work made it possible to understand how the technological tools are significant for the implementation of a process of preservation of the hydric resources in the semi-arid regions, besides exposing in a practical way the behavior of a water reservoir in a public building, enabling possible decision making from the data obtained through remote readings presented on the screen of a computer or cell phone, using a simple and low-cost tool. The results obtained were satisfactory, since the prototype is in operation since the beginning of September 2021 continuously, 24 hours a day, with an approximate value of R$ 156.00. Furthermore, it is possible to analyze the consumption of the University Prefecture, which has a daily value of approximately 5% of the reservoir volume, which is completely refilled at least once a week, never reaching levels below 90% of its capacity.
