Abstract: An espresso extraction device and an espresso extraction method are described that utilize a control unit that controls an operation of a valve unit or a pressure unit that adjusts pressure applied to an extraction unit of the device based on sensing data of a sensor unit in the extraction unit. A portafilter can be mounted on a head of the extraction unit, removing bubbles in the pressure unit by filling the pressure unit with a fluid and controlling the operation of the valve unit, removing bubbles in the extraction unit by filling the extraction unit with a fluid and controlling the operation of the valve unit, extracting espresso by exerting pressure to a fluid contained in the extraction unit by operating the pressure unit, receiving extraction pressure in the extraction unit via a sensor unit, and controlling the operation of the pressure unit on the basis of extraction pressure.

Abstract: According to an embodiment of the disclosure, an electronic device may include a sensor that is connected to a plurality of displays, and a processor that is connected to the sensor and the plurality of displays, where, when information indicating that an error occurs in a first display among the plurality of displays is obtained from the sensor, the processor may output first information to be output through the first display through a display having higher priority among remaining displays. Various other embodiments are also possible which are known from the specification.
