Abstract: A sensor with a dynamic data range. The sensor generates sensor values at consecutive time points. The sensor is configured in such a way that the data range is subjected, after each time point, to a treatment corresponding to one of the following treatment options performed as a function of the generated sensor values, wherein the treatment options include:—increasing the data range if n of the generated sensor values are outside the data range during a first time window,—decreasing the data range if m of the generated sensor values are within the data range during a second time window, and—otherwise leaving the data range unchanged. A method for automatically adjusting a data range of such a sensor is also described.

Abstract: A method for providing sensor data, including providing a maximum measuring range for the sensor, providing a first measuring range which is within the maximum measuring range, providing the sensor data in a data structure having a size that corresponds to the first measuring range, providing a second measuring range which is different from the first measuring range and is within the maximum measuring range, adapting the provided sensor data of the first measuring range for the second measuring range so that the adapted sensor data are provided in an expanded data structure having a size that corresponds to the maximum measuring range, and the provided sensor data being arranged as a function of the difference of the size between the maximum and the second measuring range and the size of the second measuring range within the expanded data structure, and the sensor-data-free sections being filled with values.

Abstract: A method for synchronizing sensors. A ratio of a first data rate of the first sensor to the second data rate of the second sensor is 2n, where n is an element from the set of natural numbers. A central timer is started. A first countdown timer is generated based on the central timer and the first data rate, and a second countdown timer is generated based on the central timer and the second data rate. The first countdown timer and the second countdown timer are started periodically. The measurement by the first sensor begins at the latest when a first latency equals the value of the first countdown timer, and the measurement by the second sensor begins at the latest when the second latency equals the value of the second countdown timer.
