Abstract:
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); and the housing (20) has only one plug connection (24), via which all required voltages and signals are passed.
