Abstract: Disclosed are an electronic device for food management and a control method thereof. A control method of an electronic device for food management includes measuring intensity of light, which is irradiated with food and reflected, by wavelengths using an infrared sensor; obtaining state information of the food based on the measured light intensity information; and adjusting at least one of temperature and humidity of an area where the food is disposed in the electronic device based on at least one of the obtained state information and preset usage plan information of the food. Accordingly, food which is managed in an optimal sate in consideration of a state of a food stored in an electronic device and a using method (consumption period and consumption method) of the food can be provided to a user.

Abstract: A washing machine and a control method therefor are disclosed. The washing machine comprises: a sensor for emitting white light, which includes infrared (IR) light, at washing water and receiving, from the white light emitted at the washing water, visible light of a specific wavelength and infrared light of a specific wavelength, which are reflected by the washing water or penetrate the washing water; and a processor for determining turbidity and the color of the washing water on the basis of the intensity and patterns of the visible light and the infrared light of the specific wavelengths, which are received from the sensor, and controlling an operation of the washing machine on the basis of the turbidity and the color of the washing water.
