WIPO Patent Application WO/2019/102660
Kind Code:

Abstract:
The present invention distinguishes odor types. This odor detection apparatus identifies an odor component (nonenal, diacetyl, isovaleric acid, etc.) included in air being measured and the concentration of said odor component on the basis of output values from a plurality of odor sensors having mutually different characteristics for reacting to odors (step S7), distinguishes the odor type (elderly body odor, odor of middle-aged overweight person, sweat, etc.) on the basis of the identified odor component and concentration of said odor component (step S8), and outputs the distinguished odor type (step S11). Specifically, a value corresponding to an odor component identified in advance and the concentration of said odor component is subtracted from the output values of the plurality of odor sensors (step S10), and an odor component included in the air being measured and the concentration of said odor component are identified on the basis of the subtracted results, these steps being repeated to identify, in order, a plurality of odor components included in the air being measured and the concentrations thereof.
