<abstract abstract-type="short" xml:lang="es"><p><![CDATA[El presente trabajo consiste en el desarrollo de un sistema de adquisición de datos para una boya oceanográfica (IIO system) que incluye los sensores necesarios para medir las variables meteorológicas y marinas, que se involucran en los procesos físicos en la interfase océano-atmósfera. El desarrollo consiste en forma general, de tres etapas: &#8226; Acondicionamiento, ya sea digital o analógico de las señales de los diferentes sensores. &#8226; Desarrollo del sistema de control del instrumento. &#8226; Desarrollo de la programación tanto de control como de comunicación instrumento-usuario. Entre las características más importantes del sistema se tienen las siguientes: &#8226; La boya cuenta con sensores para medir dirección y rapidez del viento, presión atmosférica, humedad relativa, temperatura del aire, temperatura del agua, dirección y rapidez de las corrientes marinas y amplitud del oleaje. &#8226; El sistema es programable, es decir, se pueden programar los intervalos de muestreo así como las fechas de inicio y fin de un experimento mediante una computadora personal y un programa amigable en la plataforma Windows. &#8226; El instrumento se diseñó para tener bajo consumo de energía y con un sistema de celdas solares para recargar las baterías. A la fecha se han obtenido resultados parciales con respecto a la medición de las variables oceanográficas pues aún no se ha concluido la estructura física de la boya. Es importante señalar que el desarrollo de este instrumento es pionero dentro del campo de la instrumentación electrónica oceanográfica en nuestro país, además de coadyuvar a la formación de recursos humanos de calidad.]]></p></abstract>
