I wanted to try your suggestion yesterday but couldn’t get good readings from the sensor anymore. I saw this post and since I got these exact same sensors I checked my magnets and it seems they are also axially magnetized. So I ordered diametrically magnetized ones and hope they’ll arrive in the next few days.
However: I have no idea how I got proper readings from the sensor last time. Do you have any explanation? Anyway, let’s put this thread on hold until I can check with the right magnets.
