ELECTRONIC DEVICE FOR ACQUIRING BIOMETRICS USING PPG SENSOR, AND METHOD THEREFOR

摘要

An electronic device is disclosed. The electronic device according to one embodiment disclosed in the present document may comprise: a PPG sensor comprising a light emitter to which a specified range of electric current is applied, and which is set to emit a light signal corresponding to the applied electric current, and a light detector which is set to amplify the received light signal by applying a gain value from among a plurality of gain values; a memory for storing a plurality of PPG model sets comprising electric current values corresponding to the plurality of gain values and PPG level data corresponding to the electric current values; and at least one processor electrically connected to the PPG sensor and the memory.
