Abstract

A sensor system for determining a moisture content of a fluid medium flowing in a main flow direction, e.g., an intake air of an internal combustion engine, includes: a sensor housing; at least one moisture sensor situated in the sensor housing for determining the moisture content of the fluid medium; at least one retaining element at least partially permeable to moisture; an inlet opening for channeling moisture into the sensor housing and to the moisture sensor; and at least one outlet opening situated separately from the inlet opening and channeling moisture from the sensor housing into the flowing fluid medium. The retaining element is situated in the sensor housing in such a way that the moisture sensor is acted upon by the moisture via the inlet opening and the retaining element.
