1. A method for controlling an electronic device to perform photoplethysmography detection comprising:
obtaining historical detection data of a sensor of the electronic device, wherein the sensor is a photoplethysmography sensor disposed in the electronic device, the photoplethysmography sensor comprises a plurality of light sources and at least one photoelectric sensing element, and each light source has a corresponding photoelectric sensing element;
calculating a confidence of the historical detection data;
determining, based on the calculated confidence of the historical detection data, whether a light source to be turned on by the photoplethysmography sensor in a next detection time segment comprises a light source different from a light source turned on when the historical detection data is obtained; and
determining that a photoelectric sensing element to be turned on in the next detection time segment is a photoelectric sensing element corresponding to the determined light source to be turned on.
