Abstract: An article storage apparatus includes a sensor device sensing gases included in air in a chamber where an article is stored; a concentrator concentrating the gases contained in the air; a filtering device filtering the gases contained in the air; and at least one processor. The at least one processor controls the concentrator to concentrate the gases contained in the air, and identifies a condition of the article based on a concentration level of a target gas related to the article measured by the sensor device when the target gas is extracted as gases desorbed from the concentrator pass the filtering device.

Abstract: A filtration apparatus includes a flow path, a valve provided on the flow path, a first light source configured to emit a first light including ultraviolet (UV) light toward the flow path, a second light source configured to emit a second light including visible light or infrared light toward the flow path, a first optical sensor located out of a path of the first light and the second light, electrodes provided on the flow path, and a processor electrically coupled to the valve, the first light source, the second light source, the first optical sensor, and the electrodes. The processor is configured to alternately operate the first light source and the second light source, receive a first signal from the first optical sensor while the first light source emits the first light, and control the valve and the electrodes to sterilize the flow path based on the first signal.

Abstract: Disclosed herein is an electronic apparatus and method capable of identifying a state of an object. The electronic apparatus includes a light-emitting diode array configured to transmit light beams having different wavelengths, a photodiode array configured to receive the light beams, a display, and a processor configured to control the light-emitting diode array to transmit the light beams having the different wavelengths toward an object, identify a state of the object based on intensities reflected on the object according to the light beams having the different wavelengths that are received by the photodiode array, and display information about the state of the object on the display.
