AutoCal with Hall effect not working

[c3D-Dan]

Hi,

Works Ok with Mechanical switch , but when i use a hall effect, it seems to keep sampling as the probe is retracting for an over sample. This results in ascending values for a single probe point. IE :-1.858 0.130 2.117 4.105 6.092 Any ideas?

Hello, -if you are using the shield with hall sensor, check is you are reading the digital output ( there are with both analog and digital, 4 pins) -using only the sensor ( 3 pins like small transistors) try to put a resistor between output ( witch is - output) and + from the board, it will help to stabilize the output of this electronic device. in both cases try to use shorter cables.
