Hall Effect Gauss Rating

  1. Jun 14, 2013 #1
    I know NOTHING about electronics like this. However, I am taking on a small project. I have a question that you can probably answer in half a second.

    I bought a few HE sensors, which are on their way. I need to know what activation sensitivity this HE sensor has in Gauss.


    It gives me mV/G. I will be supplying it 5V from USB.

    I will be using this calculator to determine the size magnet I need. The furthest the magnet and HE will be is 1.8-2 inches apart. http://www.kjmagnetics.com/fieldcalculator.asp

    I appreciate your help. I am hoping I don't need to purchase different HE's for this build.
