1. A sensor system for recording elements of a flow of harvested material, the sensor system comprising:
an oscillating circuit comprising at least one capacitive component with a capacitance and at least one inductive component with an inductance, wherein the oscillating circuit has a resonance frequency that depends on the capacitance and the inductance, wherein the at least one capacitive component is positioned in a region of the flow of the harvested material so that the capacitance of the at least one capacitive component is affected by the elements of the flow of the harvested material; and
a measuring device configured to determine the resonance frequency of the oscillating circuit;
wherein the sensor system is configured to deduce at least one property of the elements of the flow of harvested material based on the resonance frequency of the oscillating circuit;
wherein the at least one capacitive component comprises a flat capacitor;
wherein the flat capacitor is mounted at an edge of the flow of harvested material and is configured to detect the elements of the flow of harvested material flowing;
wherein the flat capacitor is attached to an outside of a separating rotor;
wherein the outside of the separating rotor has a grid structure;
wherein at least one flap is configured to close at least one opening in the grid structure; and
wherein the flat capacitor is attached to the at least one flap.
