Auto bed sensor

I see some auto bed leveling sensor. which one is best and how would I install it?

thank you.

BLTouch, by far. Be sure to use a genuine one, not a fake one.

question I have a new mainboard v5.4 i noticed it is different from the v5.2 how should i hook up the bltouch?

5.4 is for Mark II printers, not for the printer you have (Aldi Balco I assume). Sorry, but you are on your own with a this very unusual setup. You will also have to modify the firmware yourself.

No I’m returning it. It was marked wrong.
