The method for sensing the absolute humidity comprises steps of: connecting the microwave oven absolute humidity sensor so that the output of the amplifier is directly input into the controller; connecting the humidity sensor section parallelly with the zero balance sect. by deciding on the combination of resistance according to the counter's constant output signals (Q1-Q5) by which the reset signal and the counting clock are confirmed. After reading the voltage during the turntable's turning cycle for a predetermined number of times, determine the present humidity sensing voltage by dividing it by the number of times read. By determining the lowest value and the autocooking point during the present humidity sensing voltage, this allows the device to control the humidity sensor and to compensate noises, which prevents operating errors. As the zero balance is controlled from two output locations in the controlling sect., the structure may be simplified.
