The application of gas sensors for the measurement of environmental odor was investigated. The test chamber systems were consist of three parts, as it were, sample injection, odor sensing and data process parts. Four type of sensors were tested with regard to sensor performance like baseline stability, sensitivity and reproducibility to H₂S, CH₃SH, NH₃, and (CH₃)₃N gases. As the results, two kinds of sensors were content with the circuit conditions used in this study. In addition, the influence of relative humidity to the selected two types sensors was tested. The [mal sensor, which was appeared to be the most stable sensor against relative humidity, was selected, and applied practically to measure the real odor from the manure odor source.
