Microwave oven and method of controlling the same

A microwave oven, comprising:

• a heating unit to cook food;
• an input unit which receives a cooking condition of the food;
• a humidity sensor which measures a content of moisture generated from the food;
• and
• a control unit which sets sampling intervals to accumulate humidity values measured by the humidity sensor, and controls a cooking end time of the food according to an accumulated humidity value obtained by accumulating the humidity values measured during learned sampling intervals of the microwave oven in response to the cooking condition set through the input unit corresponding to one of previously learned cooking conditions of the microwave oven.

A method of controlling a microwave oven having a humidity sensor and a cooking chamber which receives food, the method comprising:

• setting a cooking condition of the food;
• measuring a condition of air in the cooking chamber using the humidity sensor while a cooking operation of the food is performed according to the set cooking condition;
• setting sampling intervals to accumulate humidity values measured by the humidity sensor;
• and
• comparing an accumulated humidity value obtained by accumulating the humidity values measured during the set sampling intervals with a preset value and finishing the cooking operation with respect to the set cooking condition according to the compared result.
