Abstract
A microwave oven includes a control unit which sets sampling intervals to accumulate humidity values measured by a humidity sensor, and controls a cooking end time of food according to an accumulated humidity value obtained by accumulating the humidity values measured during the set sampling intervals. Accordingly, the microwave oven prevents overcooking of the food, for example, that does not require a further cooking after initial generation of steam thereof. The microwave oven may set sampling intervals through several measurements to improve the reliability thereof. Moreover, the microwave oven may learn an operation of setting sampling intervals according to cooking conditions so as to finish a cooking according to the set sampling intervals where a later set cooking condition corresponds to the learned cooking condition.
