buy a Gauss meter with serial interface. This was done using asearch of the internet using "Gauss meter and Lanbview" as the search parameters.

Hi,

I dont really know much about 'measuring the magnetic field of the earth'.

Never had to do it, so I not sure I can offer any advice that would help you.

DIscussions should be conducted in the forum, so everybody has a chance to participate and/or learn! 🙂

You should also be more specific.

• How much accuracy do you need? For a ballpark figure, you can probably look it up in a table for your location.
• Do you need the field strenght or also the direction?

For a simple 3-axis magnetometer with computer interface, do a google search. There is plenty available, e.g.:

(Hey, if you look at the photo, it looks like the included software is already LabVIEW based! 🙂
