Abstract: A refrigerator is provided. The refrigerator includes a main body including a first door and a second door, a door opening device configured to open the first door and the second door, a first proximity sensor disposed adjacent to the first door, a second proximity sensor disposed adjacent to the second door, and a processor, and the processor may control the first proximity sensor and the second proximity sensor to operate alternately, based on sensing data obtained by the first proximity sensor and the second proximity sensor, identify a door close to an external object that approaches within a threshold distance from the refrigerator, and control the door opening device to open the identified door among the first door and the second door.
