Tips: How to install the 9-axis electronic compass sensor?

Although 9-axis AHRS with integrated E-compass can compensate for magnetic interference, users should select an environment with minimal magnetic interference for installation and operation. Keep the device as far away as possible from iron, nickel, magnets, motors, and other magnetic substances. This heading sensor is essential to strictly avoid strong magnetic materials such as magnets and electric motors in proximity to the product, as this may cause irreversible degradation of measurement accuracy. For accuracy testing, we recommend mounting the product vertically on an aluminum rod (or other non-magnetic material) and conducting forward accuracy measurements while rotating the rod perpendicular to the platform, taking care to minimize external magnetic interference.
