digital display for magnetic field - RF Cafe Forums
Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views. It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if you would like to post something on RF Cafe's Facebook page, please do.
Below are all of the forum threads, including all the responses to the original posts.

I designed a magnetic sensor for navigation purpose(2d-compass). The output of the sensor is in form of analog voltage . I want to add a digital display(for displaying corresponding magnetic field). The sensor output for zero magnetic field is zero volts, so now it must show zero Oersteds in digital display. One more example: if magnetic field is 1 Oe, output voltage is 10V, Now I want 1 Oe digital display instead of 10 V analog output.
If any one has idea about this module please do help me
Thanks and regards

As a starting point you will definitely need an ADC (Analog to Digital Converter)
