Detection of Water Ingress to an Apparatus by Resistance Measurements Between Two Electrodes

摘要

An apparatus including a first electrical arrangement that has a resistance between a first electrode and a second electrode in the absence of water and has a different resistance between the first electrode and the second electrode in the presence of water; a mechanical arrangement configured to maintain the presence of water at the first electrical arrangement; and a detecting electrical arrangement configured to detect a change in the resistance of the first electrical arrangement.
