1. An ear-wearable device, comprising:
a housing;
a microphone within the housing; and
hearing electronics within the housing configured to be connected to the microphone, the hearing electronics including at least one processor and a memory including instructions that, when executed by the at least one processor, cause the at least one processor to perform operations to:
calculate a capacitance between a terminal of the at least one processor and a designated ground plane within the housing;
obtain a temperature measurement from a sensor within the housing;
determine a humidity level within the housing using the calculated capacitance and the obtained temperature measurement;
compare the determined humidity level to one or more predetermined humidity trigger levels; and
send a notification to a wearer of the ear-wearable device conditioned on the comparison.
