In this study, a correlation analysis of odor was performed in order to assess the reliability and the field applicabilityof the Odorous gas sensor for continuous real-time monitoring. Hydrogen sulfide was found to have a correlationof 41.5~65.8%, and Ammonia is was found to have very low correlation in less than 200ppb concentration.Reactivity evaluation result, hydrogen sulfide is the reactivity was higher than the low concentration condition of100ppb or less indicated by 31.3~36.4% in the 100ppb or more high density condition based on the referencedensity value. For ammonia was very low reactivity in the low-concentration conditions below 200ppb. TVOCand composite odor assessment did not occur Reactivity no reference concentration value, the specific comparisonbetween both sensors showed a similar trend. In the same Odorous gas sensor accuracy between the result,40.3~130.6% hydrogen sulfide, ammonia, 69.1~104.9%, TVOCs is 24.7~98.6%, exhibited human odor intensityfrom 5.5~33.2%.
