1. A base plate for an ostomy appliance, the base plate comprising:
a first adhesive layer with a proximal side configured for attachment of the base plate to the skin surface of a user, the first adhesive layer having a stomal opening with a center point;
a primary angular sensing zone between a first direction and a second direction from the center point, the primary sensing zone having a first leakage electrode of a plurality of electrodes to enable detection of liquid between the first direction and the second direction; and
a secondary angular sensing zone separate from the primary angular sensing zone and between the second direction and a third direction from the center point, the secondary sensing zone having a second leakage electrode of the plurality of electrodes to enable detection of liquid between the second direction and the third direction.
