The invention relates to a sensing device for automobile windscreen air blowing control. The sensing device is characterized by comprising a control circuit, wherein the control circuit is a single chip microcomputer and is electrically connected with an infrared luminous circuit and an infrared receiving circuit; the control circuit, the infrared luminous circuit and the infrared receiving circuit are fixedly arranged in an automobile front instrument surface case; an infrared receiving tube and an infrared luminous tube are aligned with a front windscreen; the control circuit controls the infrared luminous circuit to send infrared light to the front windscreen; the infrared receiving circuit receives infrared light; when an infrared light receiving signal reaches a threshold value, the control circuit outputs a hot air or cold air starting signal through an interface; and a valve is opened for supplying the air to the front windscreen through an air passage. The sensing device has the advantage that the goal of clearing mist on the front windscreen through controlling the supply quantity of the hot air or the cold air is achieved.
