Hello to all, I'm new here und I have some problems to use a HMC5883L as a compass. During maeasuerements I see that the raspberry interferes the magnetic field. Has sombody experience in this problem? How far should th raspberry be away from the HMC5883L? And how can I avoid this poblem? Thanks in advance. Kurt
All electric devices cause magnetic interference. That's naturally.
Hello stefan us Thank you very much for this answer. But how can I avoid from this problem? How do you use this magnetometer as a compass if you have always interferences from other devices?
The coil of the DC-DC-converter propably emits dc and rf magnetic fields. The casing of the USB-connectors is made of steel and possily disturbs the earth magnetich field.
Hello Hp M, thanks for your answer, What can I do in this case. What if I try to shield the RPI with some like a cache of iron?
