Classification: CPC A | IPC A

Claim 0:
1. An electronic device comprising:
a housing;
a PhotoPlethysmoGram (PPG) sensor disposed inside the housing, wherein the PPG sensor includes:
a plurality of Light Emitting Diodes (LEDs) configured to generate light in different wavelength bands, and
a light receiving module including at least one photo diode;

a processor operatively coupled with the PPG sensor; and
a memory operatively coupled with the processor, wherein the memory includes instructions that, when executed, cause the processor to:
in response to an input requesting metering of blood glucose, identify whether the input is received within a predesignated time from a preceding metering of the blood glucose;
if the input is not received within the predesignated time from the preceding metering of the blood glucose, activate a first number of LEDs among the plurality of LEDs,
if the input is received within the predesignated time from the preceding metering of the blood glucose, activate a second number of LEDs less than the first number among the plurality of LEDs;

receive light beams generated by the activated LEDs and reflected from a user's body; and
obtain a blood glucose value of the user based at least in part on the received light beams.
