Abstract: An electronic device comprising a connector including a plurality of contacts and a liquid detection module coupled to at least one contact in the plurality of contacts. The liquid detection module can be configured to generate and apply a time varying voltage or current to the at least one contact over a range of frequencies, measure complex impedance including phase and magnitude at the at least one contact, and determine whether liquid intrusion has occurred on the contacts based on previously measured signatures of phase and magnitude versus frequency.
