HamSci PSWS Magnetometer
As part of HamSCI Personal Space Weather Station (PSWS) project, magnetometers which measure magnetic field strength and direction, are included to provide measurements of the geospace environment from the ground for both scientific and operational purposes.
Info here:
To be useful the magnetometer should be mounted in a location far from magnetic disturbances and where the temperature is as constant as possible. To that end the magnetometer is mounted remotely and buried in the ground. The PSWS uses a RM3100 magnetometer with a custom Pi interface board and a custom remote RM3100 carrier board. Weatherproof shielded ethernet CAT cable is used to carry power, control and signal information from the Pi to the magnetometer.

A small python program was written to continuously plot Y (East-West) values to help align the magnetometer to magnetic North. It's available here github.com/rkayakr/magAline
A python program was written to plot data from the magnetometer. It's available here
Here are some example results:
