Patent ID: 7864063

Claim:
A sensor arrangement for detecting moisture and/or drops of liquid on a surface of a window, the sensor arrangement comprising: a printed circuit board; a measuring capacitor provided on the printed circuit board for detecting moisture and/or drops; an analysis unit; and a second capacitor whose field lines extend into the window and is arranged on the window in order to compensate for temperature differences, said measuring capacitor comprising a first electrode and a second electrode, said second electrode being implemented as a common electrode for the measuring capacitor and for said second capacitor, said second capacitor comprising a third electrode beside said second electrode and said second capacitor being substantially configured like said measuring capacitor, wherein said second electrode has the shape of a generally stylized flattened figure eight, said second electrode is routed in such a manner about said first electrode that said first electrode and said second electrode are spaced a substantially constant distance apart and said first electrode is configured in the shape of a narrow rectangle with rounded angles.
