wherein an adhesive gasket adheres the primary printed circuit board to the housing, the adhesive gasket being positioned to prevent potting material from contacting the secondary circuit board and the sensor module casing when the housing is potted.

8. The method of claim 7 , wherein the control module activates the dispenser when the determined distance to the container is less than the predetermined threshold minus a predetermined hysteresis value and deactivates the dispenser when the determined distance to the container is greater than the predetermined threshold plus the predetermined hysteresis value.

9. The method of claim 7 , wherein the dispenser, when activated, dispenses at least one of liquid and ice into the container.

10. The method of claim 7 wherein an outer face of the sensor module casing is flush with an outer face of the housing, and wherein a protective overlay is positioned over the outer face of the sensor module casing and at least a portion of the outer face of the housing.
