Magnetometer Warning

IMPORTANT: Features requiring a magnetometer are only available on device models with magnetometers. See Product Description to verify that your device has a magnetometer.

The on-board magnetometer is provided as a convenient means to determine a heading estimate . To accurately infer sensor orientation based on a magnetic field measurement requires careful design with respect to sensor installation. Calibration is usually required post-installation, and may be difficult or impossible to achieve.

Before using the magnetometer as a heading source, it must be calibrated. Refer to the Magnetometer Calibration page for more details.
