Beschreibung
Zusammenfassung:	The invention relates to a device having an opening defining a fluid connection between a fluid channel in the device and ambient air, a sensor coupled to the fluid channel, configured to sense at least one component of the ambient air, and a micro fluid actuator connected downstream of the sensor, configured, in the suction stroke, to suck in fluid through the fluid channel and to transport the same towards the sensor, and, in the pressure stroke, to transport the sucked-in fluid through said fluid channel back towards the opening. According to the invention, the sensor is arranged spaced apart from the opening, and the volume of the fluid channel between the sensor and the opening is equal to or smaller than the stroke volume which the micro fluid actuator may convey with a single suction stroke.
