Abstract: This paper deals with the design and implementation of a measuring instrument “prototype of an electronic nose” initially used as an option for quality control of foodstuff and / or volatile compounds. The device’s function is the signal acquisition from 8 gas sensors in order to monitor and store them on a PC in the form of a matrix of data. Subsequently, a set of data is processed through software; development for samples’ classification, from a prior acquisition and pre-processing of signals.

La función del equipo es realizar la adquisición de las señales provenientes de 8 sensores de gases comerciales con el fin de monitorizarlas y almacenarlas en un PC en forma de una matriz de Datos. Posteriormente un conjunto de datos es procesado a través de un software, implementado para la clasificación de las muestras, y a partir de una previa adquisición y pre-procesado de las señales.
