Abstract

A method for detecting water level in a water tank that includes a probe voltage value acquiring step comprising periodically acquiring a voltage value of a water level probe as a probe voltage value; a voltage value comparing step that compares the probe voltage value with a stored voltage threshold value, if the probe voltage value is lower than the voltage threshold value, the method determines that the water tank level is higher than the water level probe and updates the water data to be the probe voltage value, and if the probe voltage value is higher than the voltage threshold value, the method determines that the water tank level is lower than the water level probe and updates the waterless data to be the probe voltage value; and a threshold value updating step that updates the voltage threshold value in response to the water data and the waterless data.
