In this study, the odor generated in a livestock farm with 500 heads of finisher breed in 661 m2 was monitoredduring 6 months using a gas sensor, a wired / wireless communication system and database server. Odor unit,ammonia, hydrogen sulfide, and total volatile organic compounds (TVOC) were monitored using the gas sensor. To show the tendency of odorous substances generation, the odor concentration was shown in the graph on amonthly and daily basis. Among the analysis items, the maximum generation of odor was found to be closelyrelated to the generation of hydrogen sulfide. Through observing the daily and monthly trends of odor substances,it was found that each substance was a useful indicator for monitoring odor, because ammonia, hydrogen sulfide,odor and TVOC were increased and decreased in a similar pattern. The odors were highest in the hours of theearly morning (00:00-05:00), the evening (18:00-23:00), and the morning (06:00-11:00) in a day. After the useof the microbial agent was discontinued in autumn (October), anaerobic digestion of the manure in a pit proceededand the amount of hydrogen sulfide increased. Therefore, despite a slight decrease in ammonia production, theodor unit level did not decrease after October but rather was somewhat increased. In the future, the use of theodor monitoring system is expected to improve the efficiency of odor sources management.
