Abstract
PURPOSE:To intend to improve a detecting accuracy of a human body and others, by fitting an infrared sensor so as not to include room windows and floor in a visual field of the sensor. CONSTITUTION:An infrared sensor 11 is fitted at an pre-determined height on a side wall 13 of a room 12 so that a visual field 11a of the sensor 11 is constituted to project horizontally, and vertically with a required width. And a direction of the visual field 11a is directed toward a facing side wall 14 facing the side wall 13. Thereby a floor 15 and a window 16 in the room 12 are excluded from the visual field 11a and consequently an incidence of a incident sun beam 17 into the room 12 through the window 16, into the sensor 11 directly or after reflection by the floor surface 15 is prevented. Therefore, a wrong detection of an infrared in the sun beam as one from a human body 18 can be avoided and a detection accuracy of the human body 18 and others is much improved.
