Just joined the group,was glad to see this one started!!! I have a few 3515 linear hall effect sensors,was wondering if anyone has any info on using them for a...
As a general rule, Hall effect sensors are not sensitive enough to be much in the way of a magnetometer, at least in terms of something as weak as the earth's...
... I've used the 3516 for a low gain magnetometer, it work, but not in the nanoteslas range. The chip is too noisy. But it can be used for a sensitive...
Thanks for the input! Being new to magnetometers think I'll start out with a "Jar magnetometer" :) See how that works in this area,before I get into it. radio...
I have to verify and calibrate a 3-axis RPV Magnetometer.I am looking for an article or book wich describe methods and equipment necessery for doing the...
Hi Itzahak: The classical way to to use Helmholtz coils or a long solenoid coil. The idea is that with either of these coil geometries you can calculate the...

Hi Joseph! ... avr-gcc! Ain't that cool ? ;-) And the programmer-hardware can't be more simple! Well, the programming software is command line, but let's be ...
Hi Hannes, Thanks for this!! I'm excited about trying this, but still haven't made my digikey order. Have been spending my little vacation playing around with...
Hello all and Happy New Year I'm planing to build an avr board in order to record the output of a HMC1021 magnetometer. In your schematic you use a DB25...
Bonjour Patrick! ... Yeah, I know, most programmers are using the serial port now or USB, but usually my serial ports are occupied with the RS232 of my uC...
Hi Ned! ... Way cool! Any details/schematics you can share by now ? ... You know, I've tested one flat detector at normal air pressure and it seemed to work...

Emmanouil, You mention the need to measure, "...DC current (10-70mV) occuring inside a lightly shielded environment." This statement is contradictory. Do you...
Dear Charles, Thank you for your reply. Indeed I meant to say that there there is a spike lasting 10msec (max) and in this 10msec the voltage increases from...
