An air conditioning system for a vehicle and a method for operating the air conditioning system which at least has: an air conditioner having a fan, a recirculating air flap for setting a recirculating air operation or an external air operation, a gas sensor for measuring a gas concentration, in particular a COconcentration in a vehicle cabin, and outputting a measuring signal, and a control unit for receiving the measuring signal of the gas sensor, for setting a recirculating air position or an external air position of the recirculating air flap and for controlling the gas sensor, the control unit switching the gas sensor into different operating modes in recirculating air operation than in external air operation.

Air conditioning system having a gas sensor for a vehicle and a method for operating an air conditioning system of this type

A device and a method for measuring at least one parameter of particles in a fluid, the device having a radiation source and a radiation sensor, the device having a fluid region that is in contact with the fluid; the radiation source being provided for the emission of measuring radiation according to a first direction onto the fluid region, the radiation sensor being provided for the detection of a measuring radiation reflected away from the fluid region in a second direction; furthermore, the radiation sensor having a plurality of sensor elements; and the spectral sensitivity of different sensor elements being developed differently for a wavelength-sensitive detection of the reflected measuring radiation.
