Method and sensor for detecting occurrences of wetting on a pane
The method operates with successive, continuously repeated measuring cycles. In a first cycle section, a measuring capacitor is charged up to a first threshold value by the current flowing in a light receiver of a first optical measuring section. In a subsequent, second cycle section the measuring capacitor is discharged to a second threshold value by the current flowing in a light receiver of a second optical measuring section. The light transmitters of the optical measuring sections are regulated over several measuring cycles to predetermined rated values for the charging time and the discharging time. A wetting of the pane is concluded from the momentary deviations between the rated values and the actually measured values of the charging times and discharging times. The available modulation range is adapted dynamically to the prevailing conditions by the systematic control of the intensity of the light transmitters in the two optical measuring sections. In addition, the upper limit of the modulation range is extended to higher values of the ambient light. |
