Summary:To eliminate the need for customizing an odor sensor due to an environment.SOLUTION: The present invention comprises: a sensor array 100 composed of a plurality of sensors 110 differing in characteristic sensitivity; a preprocessing unit 202 for converting each of the sensor output values acquired from the sensors 110 constituting the sensor array 100 into an output ratio that is the ratio of output values to a prescribed value; and an order assessment processing unit 204 for comparing a normal range generated on the basis of results of having performed cluster analysis on the output ratio acquired from each of the sensors 110 constituting the sensor array 100 in the past with the output ratios converted by the preprocessing unit 202 and thereby assessing whether or not the output ratios fall within the normal range.SELECTED DRAWING: Figure 1 【課題】環境によるにおいセンサのカスタマイズを不要とすることを課題とする。【解決手段】特性感度の異なる複数のセンサ110で構成されるセンサアレイ100と、センサアレイ100を構成するセンサ110から取得したセンサ出力値それぞれを、所定の値に対する出力値の割合である出力比に変換する事前処理部202と、過去にセンサアレイ100を構成するセンサ110のそれぞれから取得した出力比に対してクラスタ解析を行った結果を基に生成される正常範囲と、事前処理部202によって変換された出力比とを比較することで、出力比が正常範囲にあるか否かを判定するにおい判定処理部204と、を有することを特徴とする【選択図】図1
