LSM303DLHC interference from stepper and servo

[g3ck0]

Hi guys, I'm trying to build a gimbal-like system so I've placed the magnetometer pretty close to the motors.

When I do so, it seems to give me really wrong values (I used the Pololu heading sketch to verify). If I place the sensor about 5-6 inches away, the heading readings to me make sense again. Is there some kind of shield or technique I can use so that I can place the sensor near the motors? My contraption will look pretty poorly designed if I have to place the magnetometer on a stick away from the motors.

Any help greatly appreciated :)

Unfortunately, no. You need to keep the magnetometer well away from magnetic field sources such as motors.

So enclosing the sensor in a metal box would not make the situation any better?

A typical "Faraday Cage" is not effective at blocking static or low-frequency magnetic fields. A box constructed of superconducting material would, but it would also block the Earth's magnetic field.
