I need to use a hall effect sensor to locate a magnet using a microcontroller. Basically, the sensor will be slowly waved in front of a magnet, and I want to detect the signal using ADC.
I haven't used a hall effect before, and was wondering if anyone experienced had any tips: things to watch out for, issues with signal frequency/amplitude, effective range, amplification tips and issues, etc.
I spent some time browsing through datasheets, but surprisingly there was no output data charts . . .
