Agricultural moisture sensor with co-planar electrodes

A moisture sensor that has a drive electrode and a separate sense electrode is described. Both electrodes have surfaces that face the sensed material and the surfaces are co-planar. The drive electrode receives an excitation signal and generates an electric field that produces a current in the sense...

Beschreibung
Zusammenfassung:	A moisture sensor that has a drive electrode and a separate sense electrode is described. Both electrodes have surfaces that face the sensed material and the surfaces are co-planar. The drive electrode receives an excitation signal and generates an electric field that produces a current in the sense electrode. The current is indicative of moisture in the sensed material.
