A sensor device for detecting moisture on a roadway of a vehicle includes a housing having at least one flat housing area. The housing is constructed as a resonant body and is provided for mounting in a wheel arch of the vehicle. At least one structure-borne sound sensor is arranged in the housing area of the housing and at least one connecting means is assigned to the housing for producing a connection between the housing and the wheel arch. The at least one connecting means is constructed to be vibration damping and constructed for receiving a decoupling of the sensor device and the wheel arch. The at least one connecting means is constructed for producing a connection between the housing and the wheel arch and the structure-borne sound sensor is configured to detect only structure-borne sound signals caused by impacting moisture droplets on the housing.
