Abstract: Disclosed herein is a sensor assembly capable of detecting moisture introduced into a rack housing. The sensor assembly includes a housing, an angle sensor provided in the housing, and a moisture sensor provided in the housing. The moisture sensor includes a ground electrode, a first input electrode, a second input electrode, and a control unit electrically connected to the ground electrode, the first input electrode, and the second input electrode to detect moisture. The ground electrode, the first input electrode, and the second input electrode extend downward from the housing. A lower end of the ground electrode, a lower end of the first input electrode, and a lower end of the second input electrode are exposed to the outside of the housing. Further, the first input electrode extends downward to a different level compared to the second input electrode.

Abstract: A position sensor includes a substrate having a first surface and a second surface opposite to the first surface; an initial shaft passing through the first and the second surfaces of the substrate in a direction perpendicular to the substrate; an initial gear mounted to the initial shaft and positioned above the first surface of the substrate; a first sub-shaft positioned above the first surface of the substrate, and disposed perpendicular to the substrate and parallel to the initial shaft; a first sub-gear mounted to the first sub-shaft and positioned above the first surface of the substrate and rotatably engaged with the initial gear; a first sub-rotor mounted to the first sub-shaft and positioned above the first surface of the substrate; a first sensing coil disposed on the first surface of the substrate; a second sub-shaft positioned above the first surface of the substrate, and disposed perpendicular to the substrate and parallel to the initial shaft and the first sub-shaft; a second sub-gear mounted to
