Moisture sensor for round balers

A control system (300) for an agriculture machine (200), the control system (300) comprising:

• a moisture sensor assembly (100), in the form of a single housing, that includes at least two sensors (122, 123) and at least two apertures (116, 117), wherein a first sensor (122) of the at least two sensors (122, 123) is configured to measure a humidity inside a chamber (210) of the agriculture machine (200) and the first sensor (122) is disposed in a first sub-chamber (121) of the housing, and wherein a second sensor (123) of the at least two sensors (122, 123) is configured to measure a humidity of an operating environment external to the agriculture machine (200) and the second sensor (123) is disposed in a second sub-chamber (124) of the housing, wherein the first sub-chamber (121) is isolated from the second sub-chamber (124). wherein the moisture sensor assembly (100) includes a body, a first surface, and a second surface, the first surface positioned at a first end of the body opposite the second surface, wherein the first surface includes a first aperture (116) of the at least two apertures (116, 117) and the second surface includes a second aperture (117) of the at least two apertures (116, 117), wherein the first aperture (116) of the at least two apertures (116, 117) is positioned to allow air from inside the chamber (210) into the first sub-chamber (121) and the second aperture (117) of the at least two apertures (116, 117) is positioned to allow air from the operating environment of the agriculture machine (200) into the second sub-chamber (124), and
• an electronic controller (301) that includes an electronic processor (303) and a memory (305), the electronic controller (301) communicably coupled to the at least two sensors (122, 123),
• the electronic processor (303) configured to
• receive, from the first sensor (122), a first signal representative of the humidity inside the chamber (210) of the agriculture machine (200);
• receive, from the second sensor (123), a second signal representative of the humidity of the operating environment external to the agriculture machine (200);
• determine a moisture level of crop material in the chamber (210) of the agriculture machine (200) based at least in part on the humidity inside the chamber (210) and the humidity of the operating environment external to the agriculture machine (200);
• and
• modify operation of the agriculture machine (200) based at least in part on the moisture level of the crop material in the chamber (210).

A method for modifying operation of an agriculture machine (200) based on a moisture level of crop material, the method comprising:

• receiving crop material in a chamber (210) of the agriculture machine (200), wherein the agriculture machine (200) is a cylindrical baler (205);
• determining, with an electronic processor (303), a humidity of the chamber (210) of the agriculture machine (200) based on a first signal of a first sensor (122) of a moisture sensor assembly (100) in the form of a single housing and the first sensor (122) is disposed in a first sub-chamber (121) of the housing, wherein the first signal is representative of the humidity inside the chamber (210) of the agriculture machine (200), wherein the moisture sensor assembly (100) includes at least two apertures (116, 117), a body, a first surface, and a second surface, the first surface positioned at a first end of the body opposite the second surface, wherein the first surface includes a first aperture (116) of the at least two apertures (116, 117) and the second surface includes a second aperture (117) of the at least two apertures (116, 117);
• determining, with the electronic processor (303), a humidity of an operating environment external to the agriculture machine (200) based on a second signal of a second sensor (123) of the moisture sensor assembly (100) and the second sensor (123) is disposed in a second sub-chamber (124) of the housing, wherein the second signal is representative of the humidity of an ambient environment of the agriculture machine (200) wherein the first aperture (116) of the at least two apertures (116, 117) is positioned to allow air from inside the chamber (210) into the first sub-chamber (121) and the second aperture (117) of the at least two apertures (116, 117) is positioned to allow air from the operating environment of the agriculture machine (200) into the second sub-chamber (124), wherein the first sub-chamber (121) is isolated from the second sub-chamber (124);
• determining, with the electronic processor (303), a moisture level of the crop material in the chamber (210) of the agriculture machine (200) based at least in part on the humidity inside the chamber (210) and the humidity of the operating environment;
• and
• modifying, with the electronic processor (303), operation of the agriculture machine (200) based at least in part on the moisture level of the crop material in the chamber (210).
