Abstract
This disclosure describes improvements in moisture measurement (and related devices) that reduce variations that can occur due to surface moisture on a target object. Embodiments of the devices include a single conductive feature (e.g., a plate) and elements that can generate a moisture content value from capacitance of a target object. In one embodiment, the device can generate a signal from the fringe field capacitance. The device can use properties (e.g., frequency) of the signal to generate an output that encodes the moisture content value. The output and/or the information the output encodes may be found in a look-up table or other repository that correlates frequency to one or more pre-stored and/or pre-determined moisture content values.
