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.
