Sensor arrangement and method for the qualitative and quantitative detection of chemical substances and/or mixtures of substances in an environment

摘要

What is described is a sensor arrangement of the electronic nose type and a method for the qualitative and quantitative detection of chemical substances and/or mixtures of substances in an environment. The sensor arrangement comprises an array of sensors (10), capable of emitting a set of response signals correlated with the presence and/or concentration of at least one chemical substance, and an electronic processing and recognition system including a Boolean learning machine (34), arranged to classify the response signals generated by the sensor array (10) by the application of at least one predetermined collection of binary classification rules, adapted to discriminate between a pair of predetermined complementary outcomes of the detection.
