Abstract: A wearable device based on photoplethysmography PPG and a control method thereof are disclosed, where the wearable device includes a PPG module and a processor. The PPG module includes a plurality of light emitting diodes LEDs and a plurality of photodiodes PDs. The plurality of PDs are distributed around the plurality of LEDs in a surrounding structure. Each LED is configured to emit light signals. The LED is a tricolor integrated LED in which red light, green light, and infrared light are combined, and the light signals include a green light signal, a red light signal, and/or an infrared light signal. Each PD is configured to: receive the light signals, and transmit the light signals to the processor. The processor is configured to obtain a heart rate feature, a blood oxygen feature, and/or a respiration rate feature based on the light signals received from the plurality of PDs.
