A refrigerator may include a main body having a storage chamber formed therein, a cooling device for cooling the storage chamber, and a door for opening and closing the storage chamber. A basket may be installed at the door and a pressure sensor may be provided on the basket to detect a pressure applied by a storage item stored in the basket. A controller may output a control signal based on the pressure detected by the pressure sensor to a display that displays a residual amount of the item stored in the refrigerator.
