A method for reading data from sensors is disclosed comprising: determining a sequence of measured data over time by means of a sensor, wherein the sequence of measured data over time is generated by step-by-step changes in the measured data at input times, which are determined by an input frequency fa and have a time interval of a period 1/fa of the input frequency; reading output data from the sensor at read times, which are determined by a read frequency fs and have a time interval of a period 1/fs of the read frequency, where the read frequency fs is smaller than the input frequency fa; determining, by means of a low-pass filter of the sensor, the ratio N between the input frequency fa and the read frequency fs from the sequence over time of the numbers of input times lying between two adjacent read times.
