Abstract: This paper describes the design of a given acquisition, storage and data recorder (Datalogger SADU), with special features such as GSM / GPRS, with I2C Bus Extender, USB 2.0 communication with a computer, temperature sensor, conductivity and included dissolved oxygen, among others, these features give users an open system that allows the incorporation of a greater number of variables to compare the traditional Datalogger, Microcontroller firmware update without an external programmer, data monitoring anywhere there is coverage to the GSM / GPRS, compact design and greater versatility than most Datalogger.

Keywords: GSM Datalogger, I2C, AT commands, Visual Studio 2010, water monitoring, water quality.

Resumen: En este documento se describe el diseño de un sistema da adquisición, almacenamiento y registrador de datos (Datalogger SADU), con características especiales como: comunicación GSM/GPRS, Bus I2C con extensor, comunicación USB 2.0 con ordenador, sensor de temperatura, conductividad y oxígeno disuelto incorporado, entre otros; estas características brindan al usuario un sistema abierto, que posibilita la incorporación de un mayor número de variables a comparación de los Datalogger tradicionales, actualización del Firmware del Microcontrolador sin necesidad de un programador externo, monitoreo de datos en cualquier lugar donde exista cobertura a la red GSM/GPRS, diseño compacto y mayor versatilidad que la mayoría de los Datalogger.

Palabras Clave: GSM, Datalogger, I2C, Comandos AT, Visual Studio 2010, monitoreo de aguas, calidad del agua.
