Desenvolvimento de um sistema de telemetria via gprs de baixo custo para uma estação de monitoramento hidrológico

Abstract

Urban hydrological monitoring is an essential element for the management of modern cities. The utilization of hydrological stations opens the possibility to generate a variety of information about earth’s atmosphere, which then can be utilized to better manage environmental resources, and make more precise forecasts of the atmosphere. Although, usually, hydrological monitoring requires an expensive instrumentation system, or copyrighted software, which both implies in a high operational, acquisition and maintenance costs. Regarding these matters, this project presents the development of a low cost telemetry system, capable of remotely transmitting data from a hydrological station, via GSM/GPRS. The system also stores the data in a SD card, utilizing it as a backup if there’s a connectivity problem with the server. The obtained results have shown that the developed system is reliable for hydrological monitoring, with adequate precision and stable connection, displaying the system’s potential in remotely acquiring information.
