what’s the best way to detect the magnet? Use anther magnet. But it’s not sensitive enough. You have to feel it by youself.Right！This Hall sensor knows whether there is a magnetic object nearby or not. And it correctly tells you through ditigal output.See below picture for a quick demo!
Instead of using a hall sensor I’d recommend using a micro switch as it’d be much more reliable and easier to install on the printer. The exact process to install it will be dependent on your printer and current modifications and settings, but you should be able to find a tutorial for it online.
