An electronic nose e nose or sensor array is a software hardware system that uses a combination of multiple partially selective sensors and pattern recognition algorithms to perform gas odor . The electronic nose concept is widely used as an analytical tool in industry today the commercialization of the electronic nose began in 1993 as the concept became widely accepted as an effective instrument for detection and estimation of olfaction the book describes the general set up of an electronic nose it consists of an array of chemical sensors an air flow system which switches the reference air and the tested air a signal analysis technique and a presentation unit .
