According to an embodiment, an electronic device includes: a photoplethysmography (PPG) sensor, a temperature sensor, a memory, and a processor. The processor is configured to store first information on blood flow of a user, as associated with second information on temperature of a part of the user's body. The processor is configured to change a state of the temperature sensor from active state to inactive state. The processor is configured to identify that a first value representing the blood flow of the user is out of a first range. The processor is configured to change the state of the temperature sensor from the inactive state to the active state. The processor is configured to, based on identifying that a second value representing the temperature of the part of the user's body is out of the second range, provide a notification.

Electronic device and method for identifying body temperature of user

A ring-type wearable electronic device is provided. The ring-type wearable electronic device includes a ring-shape housing including a first housing portion and a second housing portion coupled to the first housing portion, wherein the second housing portion is configured to contact a finger of a user wearing the ring-type wearable electronic device, a first light source including a plurality of light emitters disposed in the ring-shape housing, and configured to emit light of red wavelength and infrared wavelength bands towards the finger, a first sensor disposed in the ring-shape housing, and configured to receive light emitted by the first light source, a second sensor disposed in the ring-shape housing, and configured to receive light emitted by the first light source, wherein the first sensor is positioned farther from the first light source than the second sensor is positioned from the first light source, a flexible printed circuit board (FPCB) disposed in the ring-shape housing, wherein the first light source, the first sensor, and the second sensor are disposed on the FPCB at least partially bent corresponding to the ring-shape housing, at least one processor including a processing circuitry, and memory storing instructions, wherein the instructions, when executed by the at least one processor individually or collectively, cause the ring-type wearable electronic device to: emit, by the first light source at a first time, first light of red wavelength and infrared wavelength bands, the first light being configured to reach the first sensor through the finger, based on the first light emitted by the first light source at the first time, obtain first information corresponding to part of the first light that is received by the first sensor via the finger, emit, by the first light source at a second time different from the first time, second light of red wavelength and infrared wavelength bands, the second light being configured to reach the second sensor through the finger, based on the second light emitted by the first light source at the second time, obtain second information corresponding to part of the second light that is received by the second sensor via the finger, and acquire an oxygen saturation information of the user based on at least one of the first information or the second information.
