Apparatus and method for removing the influence of microwave noise, without any shielding parts, thus increasing the reliability of detected humidity information. According to the invention, the cumulative difference of humidity values sensed by a humidity sensor is calculated for each half period of a commercial alternating current frequency, oscillating and non-oscillating terms of a magnetron are determined by comparing the calculated cumulative differences with each other, and the humidity-sensed values obtained during the determined non-oscillating terms of the magnetron are used as humidity information for automatic cooking control. In order to even further remove the influence of the microwave noise, the humidity sensor may include capacitors for bypassing the microwave noise introduced into the sensor.
