Do nearby electrical currents interfere with sensors?

It is possible that strong DC electrical currents can influence the accuracy of the orientation measurement of the MotionTracker as a DC current generates a (static) magnetic field. In practice currents below 1 A do not significantly influence the MotionTracker if the distance between the wires and the MT is more than a few centimeters. If this is a problem in your application, consider using twisted-pair wires which will practically eliminate any radiated field.

Strong power surges, such as those caused by the ignition when starting an engine, can corrupt the serial communication or disturb the internal electronics.
