Abstract
A moisture sensor includes one or more electrodes and sensor circuitry configured to detect the presence of moisture by detecting a change in an electrical measurement of the one or more electrodes. In response, the sensor may signal a component to perform an action. In some examples, capacitance and/or resistance between a pair of electrodes may be monitored, such as a pair of electrode sheets or meshes positioned in passage of a device that are separated by a gap. In various examples, a first electrode may be mounted cantilever to a second electrode and the presence of moisture between the electrodes may pull a free end closer to the second electrode. In some examples, the presence of moisture may cause bridging of a gap between two or more electrodes to complete or corrosion of a portion of an electrode to result in a change of resistance that can be detected.
