Abstract
A sensor device includes at least one first sensor element that generates a first sensor signal based on sensing a varying magnetic field; at least one second sensor element that generates a second sensor signal based on sensing the varying magnetic field; a signal tracking circuit that generates a trigger signal having trigger pulses that are generated based on crossings of the first sensor signal with an adaptive threshold and extracts vibration relevant information using the first sensor signal and the second sensor signal; an output controller that generates an output signal having output pulses that are triggered by the trigger pulses during a non-vibration event and suppress the output pulses during an entire duration of a vibration event; and a vibration detection circuit that detects the vibration event based on the extracted vibration relevant information and indicates the vibration event to the output controller.
