Abstract: A device, method, and system for determining a moisture level of for an agriculture machine. receiving crop material in a chamber of the agriculture machine. Determine a humidity of the chamber of the agriculture machine using a first signal of a first sensor of a moisture sensor assembly. The first signal is representative of humidity inside the chamber. Determine a humidity of an operating environment external to the agriculture machine using a second signal of a second sensor of the moisture sensor assembly. The second signal is representative of the humidity of an ambient environment of the agriculture machine. Determine a moisture level of the crop material in the chamber of the agriculture machine using the humidity inside the chamber and the operating environment. Modify operation of the agriculture machine based at least in part on the moisture level of the crop material in the chamber.

Abstract: A combine harvester for harvesting crop including a header, to cut crop, and a feeder house having an inlet, connected to the header, and an outlet, wherein the feeder house defines an interior and an exterior located outside the feeder house. The combine harvester includes one or more sensor assemblies connected to the feeder house, wherein each of the sensor assemblies provides a relative humidity value or both of a relative humidity value and a temperature value. A controller is operatively connected to the plurality of sensor assemblies, wherein the controller receives the relative humidity value or temperature value from each of the plurality of sensor assemblies. In response to the received relative humidity value or temperature value, the controller identifies a recommended setting for one or more harvester devices, parts, or components, to avoid grain loss and grain breakage resulting from crop moisture conditions.
