Electronic device including a plurality of temperature sensors

A method of a wearable electronic device for measuring a body temperature of a user wearing the wearable electronic device comprising a contact-type temperature sensor and a non-contact-type temperature sensor including an IR emitter, the method comprising:

• measuring a first temperature of a portion of a housing of the wearable electronic device using the contact-type temperature sensor disposed at the portion of the housing;
• measuring, using the non-contact-type temperature sensor, a second temperature of an area of an exterior surface of the wearable electronic device by emitting IR light by the IR emitter to the area, wherein the area of the exterior surface corresponds to the portion of the housing;
• identifying information on a heat flow based on the first temperature and the second temperature during a specific period,
• measuring, using the non-contact-type temperature sensor, a third temperature of the user by emitting IR light by the IR emitter toward a skin of the user through a transparent window of the housing;
• and
• determining a current body temperature based at least on the information on the heat flow during the specific period and the third temperature.

A wearable electronic device comprising:

• a housing comprising a first plate including a first surface forming an exterior surface of the wearable electronic device;
• at least one processor;
• memory;
• and
• at least two temperature sensors, including a contact-type temperature sensor and a non-contact-type temperature sensor including a IR emitter,
• wherein the contact-type temperature sensor is disposed at a portion of the housing, and is configured to measure a first temperature of the portion of the housing,
• wherein the non-contact-type temperature sensor configured to emit IR light to an area of the first surface to measure a second temperature of the area, wherein the area of the first surface corresponds to the portion of the housing, and
• wherein the memory stores instructions that, when executed by the at least one processor individually or collectively, cause the wearable electronic device to:
• identify information on a heat flow based on the first temperature and the second temperature during a specific period, and
• measuring, using the non-contact-type temperature sensor, a third temperature of the user by emitting IR light by the IR emitter toward a skin of the user through a transparent window of the housing;
• and
• determine a current body temperature based at least on the information on the heat flow during the specific period and the third temperature.
