Abstract
A turbidity sensor is built in at a location being reachable by washing fluid in an automatic washing machine having a microprocessor for process control, a light transmitter and a light receiver for transmitting light through the washing fluid in a measurement path. A method for temperature compensation of measured values of the turbidity sensor includes calculating a temperature coefficient of the turbidity sensor for each operating point and storing the temperature coefficient in memory as a correction value in software for evaluating measurement results of the turbidity sensor. A respective measurement result is corrected by using the temperature coefficient as a function of a temperature being present and measured at the turbidity sensor.
