Abstract: The present invention relates to a refrigerator and, more specifically, a refrigerator which enables a user to easily open a door thereof. The present invention relates to a refrigerator and method for controlling the same, which can prevent a door thereof from opening by itself due to a malfunction. According to an embodiment of the present invention, a refrigerator may comprise: a cabinet having a storage chamber; a door for closing or opening the storage chamber; a sensor provided to sense whether a user is within or out of a sensing distance, to enable discrimination between sensing-on and sensing-off; a door opening device provided to automatically open the door; and a control unit for determining an operation condition of the door opening device on the basis of a time interval from the sensing-on to the sensing-off and a duration for which the sensing-on continues in the sensor, so as to control the operation of the door opening device.
