1. A sensor assembly part for attachment to a base plate of an ostomy system, the sensor assembly part comprising:
an adhesive layer having a distal side and a proximal side, the proximal side being configured for attachment to a skin surface of a user;
a plurality of electrodes arranged entirely on the distal side of the adhesive layer; and
a masking element arranged between the plurality of electrodes and the adhesive layer, the masking element comprising a plurality of openings, wherein each opening of the plurality of openings:
exposes a portion of an electrode of the plurality of electrodes to define a corresponding sensor point; and
the corresponding sensor point is configured to permit output to propagate through the opening and contact the electrode.
