Characterization of Unpleasant Odors in Poultry Houses

In this study, the ability of an electronic nose developed to analyze and monitor odour 15 emissions from three poultry farms located in Meknes (Morocco) and Berlin (Germany) was evalu16 ated. Indeed, the potentiality of the electronic nose (e-nose) to differentiate the volume fractions of 17 hydrogen sulphide, ammonia and ethanol is investigated. Furthermore, impact change of relative 18 humidity values (from 15% to 67%) on the response of gas sensors has been reported and reveals 19 that the effect remains less than 0.6%. Furthermore, the relevant results, confirmed that the devel20 oped e-nose system was perfectly classify and monitor the odorous air of poultry farms. 21
