An infrared array sensor device capable of detecting an existence, acting amount, a location, and a direction of a human body is disclosed. In the sensor device, a Fresnel lens(101) condenses infrared light. A guide(102) divides the infrared light condensed by the Fresnel lens(101) into correcting sections and guides the incidence thereof. A filter(105) filters infrared light of a predetermined wavelength from the incident infrared light guided through the guide(102). A pairs of infrared sensing elements(108,112) are arranged in guide directions corresponding to guide directions of the filtered infrared light from the filter(105) and sense the filtered infrared light. A circuit section(111) processes output signals of infrared sensing elements(108,112). |
