a second window forming at least a portion of the second surface of the protrusion;
a first board disposed inside the housing;
a second board electrically connected to the first board;
a first sensor circuit mounted on a first surface of the second board facing the first direction, disposed in the protrusion, and configured to obtain a first biometric signal through the first window; and
a second sensor circuit mounted on a second surface of the second board facing the second direction, disposed in the protrusion, spaced apart from the second window, and configured to obtain a second biometric signal through the second window,
wherein a type of the first biometric signal is different from a type of the second biometric signal.

2. The electronic device of claim 1 , wherein the first board includes a printed circuit board, and the second board includes a flexible printed circuit board.

3. The electronic device of claim 1 , further comprising a hole connecting an internal space of the housing and an internal space of the protrusion.

4. The electronic device of claim 3 , wherein the second board passes through the hole from one surface of the first board and is disposed in the internal space of the protrusion.

5. The electronic device of claim 1 ,
wherein the first biometric signal comprises a fingerprint of a user; and
wherein the second biometric signal comprises a heart rate of the user.

6. The electronic device of claim 1 , further comprising at least one of an illuminance sensor d/or a light source mounted on the first surface of the second board.

7. The electronic device of claim 6 , wherein the first sensor circuit and the second sensor circuit mounted on the second board are electrically connected to a processor mounted on the first board.

8. The electronic device of claim 7 , wherein the processor is configured to:
detect whether a body portion of a user is placed on the first window through the illuminance sensor,
when the body portion of the user is placed on the first window, activate at least one of the first sensor circuit or the second sensor circuit, and
obtain at least one of the first biometric signal or second biometric signal through at least one of the first sensor circuit or the second sensor circuit.

9. The electronic device of claim 8 , wherein the first sensor circuit includes a fingerprint sensor, and wherein the processor is configured to:
emit, in response to detecting a finger of the user on the first window, light to the user's finger through the light source; and
obtain fingerprint information of the user based on receiving, through the fingerprint sensor, the emitted light that has been reflected by the user's finger detected on the first window.

10. The electronic device of claim 9 , wherein the fingerprint sensor is an optical fingerprint sensor, and a lens is applied to the first window and/or the second window and configured to increase an area for collecting light reflected by the finger.

11. The electronic device of claim 8 ,
wherein the second sensor circuit includes a heart rate sensor; and
wherein the processor is configured to obtain heart rate information of the user based on emitting light toward a wrist of the user through a light emitting part of the heart rate sensor and receiving the emitted light that has been reflected by the user's wrist through a light receiving part of the heart rate sensor.

12. An electronic device comprising:
a housing;
a protrusion from a side surface of the housing, the protrusion comprising a first surface facing a first direction and a second surface facing a second direction perpendicular to the first direction;
