1. A sensor unit for vehicles for detecting at least a moisture and/or a temperature on an inside of a vehicle window by at least one sensor, the sensor unit configured to be mounted in contact with the inside of the vehicle window, the sensor unit comprising:
a housing, the sensor unit being partially enclosed by the housing, the housing comprising at least one opening in a direction of the vehicle window through which the sensor unit is pressed against the vehicle window;
a printed circuit board that is pressed against the inside of the vehicle window when the sensor unit is in a mounted state, the printed circuit board being arranged between the at least one sensor and the vehicle window, the printed circuit board being a rigid-flexible printed circuit board comprising a bend at least in a partial region, the bend of the rigid-flexible printed circuit board being set up in such a way as to generate an elastic restoring force, which presses the rigid-flexible printed circuit board against the vehicle window,
wherein the rigid-flexible printed circuit board comprises at least one recess for receiving a fixing means,
wherein the rigid-flexible printed circuit board has a substantially elongate shape,
wherein the at least one recess and the fixing means are collectively configured to hold the rigid-flexible printed circuit board in a specific shape, and
wherein the at least one recess has an elongate shape which extends substantially parallel to a longitudinal direction of the rigid-flexible printed circuit board and is configured to adjust a height of the rigid-flexible printed circuit board.
