The magnetometer indicates yaw angle and heading, but only if hard-iron offset is compensated and when there

is no additional magnetic field around the

Sensortile.box

disturbing the measurement.

The gyroscope indicates the new orientation based on the previous one, when its bias is compensated by the

accelerometer. The gyroscope can detect the static condition of the Sensortile.box,
