Abstract

The embodiment of the application discloses PPG sensor, this PPG includes first PD, first LED and second LED, wherein, the distance between first PD and the first LED and the distance between first PD and the second LED are not equal. As such, in the PPG sensor, the distance between two PDs and LEDs of different sizes may be formed. The distance between these two different PDs and LED can satisfy the requirement to distance between PD and the LED under the different application scenes, specifically, this PPG sensor can compromise four kinds of application demands such as static heart rate measurement, dynamic heart rate measurement, wear elasticity detection and blood oxygen measurement. Based on this, this application embodiment still provides a smart watch or bracelet including this PPG sensor.
