Abstract: The invention relates to a sensor arrangement for detecting ambient conditions, in particular for a motor vehicle, with at least one carrier plate and optical elements arranged on this carrier plate, wherein several of the optical elements are arranged around a shared central region on the carrier plate, and at least two of the optical elements arranged around the central region exhibit primary action axes. These primary action axes are adjusted at a predetermined angle relative to the carrier plate, wherein the primary action axes are directed toward the shared central region. Additional sensors arranged on the carrier plate include a rain sensor, a solar sensor as well as various light sensors, which preferably are arranged on receiving surfaces of the carrier plate.

Abstract: The invention relates to a method for detecting the visibility outside of a motor vehicle by means of at least two light sensors, in the case of which the intensity of the light reflection of the driving light emitted in the direction of travel is detected by means of a first light sensor, which is oriented in the direction of travel. The first light sensor thereby transmits at least a first evaluation signal to a control unit for further processing at least as a function of the recorded intensity of the light reflection. The ambient light is detected by means of a second light sensor and a second evaluation signal is transmitted to the control unit as a function of the intensity of the ambient light. The control unit correlates the evaluation signals of both light sensors and the light intensity threshold value is determined on the basis thereof.
