Abstract: A refrigerator may include: a communication device, an object detection sensor for sensing an object positioned within a predetermined region around the refrigerator door; and a controller for controlling the refrigerator to operate in a specific mode based on a connected state between the communication network and preset mobile terminals. If an object sensing signal is received from the object detection sensor in the specific mode, the controller may send a notification to at least one of the preset mobile terminals through the communication network.
