Device designed for environment detection

The invention relates to a device (1), designed for detecting the surroundings of a vehicle. In this case, the device (1) has a sensor (100) with a cover (10) for a transmission window and / or a reception window (15) of the sensor (100). In addition, the device (1) has at least one air nozzle (50) with an air inlet (30) and an air outlet (40), wherein the air nozzle (50) is adapted to draw air (20) by means of the air inlet (30) and the Injected air by means of the air outlet (40). The at least one air nozzle (50) is arranged relative to the cover (10) of the transmission window and / or the receiving window (15) of the sensor (100) in such a way that the air (25) emitted from the air outlet (40) of the air nozzle (50) ) is directed along an outer surface of the cover (10) of the transmitting window and / or the receiving window (15) of the sensor (100). The air inlet (30) of the air nozzle (50) is directed in a horizontal direction of movement (60) of the vehicle and arranged such that the drawn-in air is drawn when moving the vehicle from the ambient atmosphere of the vehicle.
