Method for the determination of Odor intensity and Electronic nose for it

摘要

This refers to a method for the determination of Odor Intensity by means of an electronic nose as the electronic nose to do it. The novelty of the method consists in the recognition of the intensity of aroma through a Prior process of parameterization of Sensors and then implement it in the Controller of the nose.The Method consists in Sampling the same smell aromas but different Intensity affect the signals of the Sensors to the parameters are increasing in Correspondence to the growing intensity of aromas, Interpolate values affected the Sensors to obtain a formu The schedule for the nose which is used to determine intensities.With this formula to obtain the value of the intensity and show these results through a Visualization System.The Electronic nose to the present, is portable, consists of a Chamber accommodating oftatomu00e9tricos Sensors that respond to the aromas, a Pump to circulate the gas containing aroma measure, a Controller for processing the signals of Sensors and communicate the result Two measurements, a system of Light and Sound display.An application of this is the determination of smells that indicate the State of Preservation of food.
