Water bodies play a fundamental role in the development of society. The construction of dams for water storage has been carried out since ancient civilizations and, along with the development of modern society, new forms of construction have emerged. Over time, these constructions led to improvements for the population which, in turn, took the price of changing the environment and its effects. On this paper a water level audit system was developed with hardware for sensing and sending the data through the cellular network to a server for storage and later displaying it to the user so that he doesn't need to go back to the essay location, being useful for research on the local hydraulic system. © 2024 Elsevier B.V., All rights reserved.
