Data (e.g. DATA 1) can be received.

The first auxiliary processor 410 can recognize the open/closed state based on sensing data transmitted from the hall sensor 430 and calculate the folding angle in real time. Although not shown in the drawing, the first auxiliary processor 410 may calculate the folding angle by collecting data received from sensors other than the Hall sensor 430 (eg, a gyro sensor, an acceleration sensor).

Alternatively, it may be transmitted to the outside (eg, the first auxiliary processor 410 or the second auxiliary processor 420) through the second data line 445.

As an example, the Hall sensor 430 may measure a magnetic field in a first direction, a magnetic field in a second direction perpendicular to the first direction, and a magnetic field in a third direction perpendicular to both the first and second directions. The first auxiliary processor 410 or the second auxiliary processor 420 can recognize the open/closed state of the electronic device depending on whether the change in magnetic force value exceeds a specified value based on one axis where the change in magnetic force value occurs. .
