1. Device, in particular for use in a motor vehicle, having a sensor arrangement ( 21 ), which controls an air-conditioning unit, for determining ambient-air quality, and an arrangement of ozone sensors ( 21 , 22 ) upstream and downstream of a radiator ( 1 ), in particular of the motor vehicle, whic
1. Device, in particular for use in a motor vehicle, having a sensor arrangement ( 21 ), which controls an air-conditioning unit, for determining ambient-air quality, and an arrangement of ozone sensors ( 21 , 22 ) upstream and downstream of a radiator ( 1 ), in particular of the motor vehicle, which is coated with a catalyst material for detecting conversion rate of conversion of ozone into oxygen which is brought about by the catalyst;wherein both the sensors ( 21 ) of the sensor arrangement and ozone sensors ( 22 ) are connected to a common control unit ( 7 ), which processes the signals from the sensors;a first airstream ( 3 , 5 ) and a second airstream ( 4 , 6 ), in which the ozone sensor ( 22 ) for determining the ozone level downstream of the radiator ( 1 ) is arranged, are guided in passages ( 5 , 6 ) which are arranged in a common housing, ( 20 ), wherein the control unit ( 7 ) is also arranged in the common housing ( 20 ); andthe housing ( 20 ) has only one plug connection ( 24 ), via which all required voltages and signals are passed. 2. Device according to claim 1, wherein the sensor arrangement ( 21 ) for determining the air quality and the ozone sensor for determining ozone level upstream of the radiator ( 1 ) are arranged in a common first airstream ( 3 , 5 ). 3. Device according to claim 2, wherein the first airstream ( 3 , 5 ) and a second airstream ( 4 , 6 ), in which the ozone sensor ( 22 ) for determining the ozone level downstream of the radiator ( 1 ) is arranged, are guided in passages ( 5 , 6 ) which are arranged in a common housing ( 20 ). 4. Device according to claim 1, wherein the sensors ( 21 , 22 ) have heating elements which are controllable by the control unit ( 7 ). 5. A method for use in a device according to claim 1, wherein measured values from the ambient-air quality sensor arrangement ( 21 ) are used to compensate for measurement inaccuracies of the ozone sensors ( 22 ) resulting from cross-sensitivities of the ozone sensors ( 22 ). 6. The method for use in a device according to claim 5, wherein the measured value from the ozone sensor arranged upstream of the radiator ( 1 ) is also taken into account for determination of the ambient-air quality.
