Magnetic sensor device and method for operating a magnetic sensor device

Abstract

The present invention relates to a magnetic sensor device (50) comprising a sensor unit (52) designed such that the sensor unit (52) can output an analog signal (54) of a periodically varying magnetic field strength of an external magnetic field in at least one predetermined spatial direction, an analog-to-digital converter (60) by means of which the respective analog signal (54) can be converted into a respective digital signal (62), and an evaluation unit (72) designed and / or programmed such that the evaluation unit (72) can determine a measured value (74) of the respective magnetic field strength taking into account the respective digital signal (62), wherein the magnetic sensor device (50) comprises, either as part of the evaluation unit (72) or separately from the evaluation unit (72), a frequency determination unit (84) designed and / or programmed such thatthat by means of the frequency determination device (84) a respective frequency or period (86) of the respective periodically varying magnetic field strength can be determined taking into account the respective analog signal (54) or digital signal (62).
