    I'm building a gaussmeter and I'm looking for a very sensitive ratiometric hall sensor. I need it to measure dc fields up to about 800 gauss , but I want as good of a resolution as possible, maybe .01 gauss. I'm not the most educated on sensors , so when I read the schematics on each one, I cannot figure out if they are sensitive enough. The only info most give on sensitivity is how many millivolts/ gauss.
    If anyone can recommend a hall ratiometric sensor that fills these specs, I would appreciate it greatly.

    Degree of product familiarity. . . .Hall sensors

    I want as good of a resolution as possible, maybe .01 gauss.

    That would be akin to me weighing myself and then stepping up again with a turkey feather in hand and expecting a frational readout increment .

    The Earth's magnetic field varies from 0.25 to 0.65 gauss. You're also going to need some real good shielding.....
