Ground sensor
First Claim
1. An agricultural driven machine, comprisinga soil sensor for surveying the condition of a substrate,wherein the soil sensor includes at least one transmitting coil and at least one receiving coil,wherein the transmitting coil is arranged to generate an electromagnetic primary field and the at least one receiving coil is arranged to receive the electromagnetic secondary field induced in the substrate by the primary field,wherein the transmitting coil and the at least one receiving coil are arranged in a housing which includes electromagnetic radiation shielding material,wherein the soil sensor is mounted on a front lifting mechanism of the driven machine,wherein during a work run of the driven machine, soil parameters of a soil section are detected,wherein for calibration of the soil sensor, a static measurement without a driven machine is first performed and, based on background noise detected in the static measurement, a static offset is determined, and consequently, signals detected during the work run are corrected by the static offset.

Abstract
A device for surveying the condition of a substrate, in particular a soil sensor, having at least one transmitting coil and at least one, preferably four, receiving coils. The transmitting coil is arranged to generate an electromagnetic primary field and the receiving coil is arranged to receive the electromagnetic secondary field induced in the substrate by the primary field. The transmitting coil and the receiving coil are arranged in a housing which includes electromagnetic radiation shielding material. Also disclosed is an agricultural driven machine including a soil sensor and a method for operating a driven machine.
