1. A sensor patch for attachment to a base plate of an ostomy appliance, the sensor patch comprising:
a sensor assembly layer comprising a plurality of electrodes including a first electrode and a second electrode for forming a first sensor;
a first adhesive sensor layer forming a distal side of the sensor patch and being adapted for attachment of the distal side of the sensor patch to the proximal surface of the base plate, wherein the first adhesive sensor layer comprises a first centre portion having a first centre thickness and a first outer rim portion surrounding the first centre portion, wherein the first outer rim portion has a first outer rim thickness decreasing along a radial direction from adjacent the first centre portion to a first outer periphery of the first adhesive sensor layer, and wherein the first outer rim thickness adjacent the first centre portion is the first centre thickness and the first outer rim thickness at the first outer periphery of the first adhesive sensor layer is a first minimum outer rim thickness, wherein the sensor patch comprises a stomal opening with a centre point, the stomal opening being configured to allow passage of output through the stomal opening and into an ostomy pouch attached to the base plate.
