摘要： A sensor device of the present invention is capable of surely detecting occurrence of a fire and a type of the fire. The sensor device includes a detection element made of an organic semiconductor element or an inorganic semiconductor element which is varied in characteristic value (i.e., resistance) thereof by both gas produced in a flaming-type fire and a smouldering-type fire and of which a variation in resistance by gas produced in a flaming-type fire is different in polarity from that by gas produced in a smouldering-type fire. A resistance of the detection element is extracted by a resistance extractor and then fed to a resistance decrease discriminator and a resistance increase discriminator, wherein a decrease or increase in resistance of the element is discriminated. An information output circuit outputs a predetermined signal depending on discrimination results provided by the discriminators, to thereby detect occurrence of a fire and/or a type of the fire.
