Abstract
A wearable electronic device for detecting biometric information is provided. The device includes a motion sensor, one or more optical sensors including a light emitting unit and a light receiving unit, and at least one processor configured to obtain a first motion signal corresponding to the wearable electronic device, prior to a biological signal being obtained, emit light using the light emitting unit based on a determination that the first motion signal satisfies a specified condition, obtain the biological signal corresponding to a user using the light receiving unit based on reflected light which the light is reflected on the user, obtain, using the motion sensor, a second motion signal corresponding to the wearable electronic device during the obtaining of the biological signal, and refrain from the emitting of the light, based on a determination that the second motion signal does not satisfy the specified condition.
