Abstract: A wearing prompt method for a wearable device and an apparatus, and related to the field of communications technologies, to reduce a probability that the wearable device cannot accurately measure physiological parameters of a user, thereby improving accuracy of measuring the physiological parameters of the user. The method includes: obtaining, by the wearable device, a target PPG (photo plethysmo graph) signal; and prompting, by the wearable device when the target PPG signal is inconsistent with a stored reference wearing parameter, a user to adjust a wearing position of the wearable device and to adjust tightness of wearing the wearable device.

Abstract: A photoplethysmography sensor is provided. The sensor includes a housing, a cover plate, an optical device configured to emit light outwards, and a photoelectric sensor configured to receive an external optical signal. The housing and the cover plate form an enclosed space, and the optical device and the photoelectric sensor are accommodated in the enclosed space. The cover plate includes a first area used by the optical device to emit the light outwards and a second area used by the photoelectric sensor to receive the external optical signal. The cover plate further includes a third area and a shielding structure disposed on the third area, and the shielding structure is configured to isolate light between the optical device and the photoelectric sensor. The shielding structure is disposed in the third area so that isolation between the optical device and the photoelectric sensor is improved.
