the PPG sensor converts light signals into electrical signals and then into digital signals by emitting the light signals towards the skin and receiving the light signals reflected by the skin tissue. Because blood flows in the blood vessel and the absorption of light changes, the obtained digital signals are divided into direct current signals and alternating current signals on the premise that the absorption of the blood vessel to light changes and the absorption of other tissues to light basically does not change, and the alternating current signals can be used for reflecting the characteristics of the blood flow by extracting the alternating current signals.

Because the human capillary vessel in duct position is abundant, and skin is thinner, simultaneously, the effect of shielding when the earphone is worn is preferred to can reduce external light signal to the interference of measuring, the photoelectric data that adopts the earphone to combine the PPG sensor to detect is comparatively accurate, and the heart situation that further detects is also comparatively accurate.

To solve the problem, when the heart test information is in the preset interval, the user is reminded to more accurately detect the heart health state by timely adopting the ECG electrode. The preset interval is an interval in which preset heart test information is abnormal.
