Health detection method and device based on air conditioner indoor unit

The invention provides a health detection method and device based on an air conditioner indoor unit. According to the method, an air conditioner indoor unit is provided with a recognition module used for detecting the oxyhemoglobin saturation and a processor; the processor is used for executing the following method: acquiring a light current signal corresponding to a to-be-detected object acquired by the identification module; a pulse waveform is obtained based on the photocurrent signal, and a pulse frequency is obtained based on a wave crest interval corresponding to the pulse waveform; obtaining oxyhemoglobin saturation information based on the photocurrent proportion of the red light and the infrared light in the photocurrent signal; and based on the change characteristics of the pulse frequency and the change characteristics of the blood oxygen saturation information, determining a health state corresponding to the to-be-detected object. According to the health detection method based on the air condition
