Abstract: An optical sensor includes a light-emission unit, a controller, a light-reception unit that receives a first reflected light which is reflected at the transparent plate and a second reflected light that is reflected at an external object outside of the transparent plate, a calculator that, based on the light received by the light-reception unit, calculates whether an adhered substance is adhered to the transparent plate, and calculates a relative position of the external object, and a fixing portion that fixes the light-emission unit and the light-reception unit with respect to the transparent plate, wherein the calculator calculates whether the adhered substance is adhered to the transparent plate and calculates the relative position of the external object based on the light received by the light-reception unit.

Abstract: In a light sensor, an operational determination circuit determines based on first and second intensity signals respectively indicative of intensities of light irradiated from above and ahead of a vehicle whether the vehicle is positioned under a shield structure, determines whether it is necessary to turn on a light in the vehicle for the shield structure, and outputs a result of determination as a determination signal. A communication output circuit receives the first intensity signal and the determination signal, and outputs information to a control unit whether it is necessary to turn on the light for the shield structure when the vehicle is positioned under the shield structure.
