A sensing device and interactive components are provided for the continuous automatic monitoring of the moisture content of hay during its baling with a conventional baling machine. The device is comprised of a cylindrical holding tube having an open forward extremity which is welded to the retaining wall of the compression zone of the baler. An electrode and surrounding electrical insulative material are disposed within the holding tube. The forward extremities of the electrode and insulative material extend through an aperture in the retaining wall to coplanar disposition with the interiorly directed surface of the retaining wall. As the hay slides perpendicularly past the electrode, electrical resistivity is measured and caused to indicate moisture content on a meter located in the driver's compartment of the baler machine.
