Tips: Precautions for installing 2D electronic compass module

Although the SCM220 electronic compass module can compensate for magnetic interference, users should choose an environment with minimal magnetic interference for installation and use. It is recommended to install 2D electronic compass module away from iron, nickel, magnets, engines, and other magnetic materials. If these magnetic sources are present nearby, maintain a minimum distance of 0.5 meters. To ensure optimal measurement accuracy, use non-magnetic screwdrivers and non-ferrous screws during installation. Strong magnetic materials (such as magnets and electric motors) should be kept at least 10 cm away from the compass, as closer proximity may cause irreversible degradation of measurement accuracy.

Each electronic compass module comes with a 10 cm cable, with an optional length depending on user needs. While 2D electronic compass module can compensate for magnetic deviation in a stable magnetic environment, it cannot compensate for changing magnetic interference. For example, wires carrying DC current generate a magnetic field, and if the current changes, the magnetic field strength will vary accordingly. Batteries are another potential source of changing interference. Since each installation environment will have a different magnetic field, users must evaluate the feasibility of installation in their specific environment.

The compass module has a heading accuracy of 1°, which has been rigorously verified. Proper scientific testing methods are equally crucial. Our recommended testing method is to mount it on a vertical aluminum (or other non-magnetic material) rod for heading accuracy measurement. Ensure the rod is perpendicular to the rotating platform, and minimize the influence of large external magnetic fields during the test.
