Abstract
A method for operating a sensor device for detecting an object. including measuring a magnetic field using a magnetic field sensor to ascertain a measured value, the sensor unit being deactivated during the measurement, computing a first distance of the measured value from a first reference measured value that corresponds to a magnetic field when a measuring range is free of an object, computing a second distance of the measured value from a second reference measured value that corresponds to a magnetic field when an object is situated in the measuring range, activating the deactivated sensor unit as a function of the computed distances, carrying out a propagation time measurement using the activated sensor unit to ascertain sensor data that correspond to the propagation time measurement, and ascertaining, based on the sensor data, whether an object is situated in the surroundings of the sensor device.
