Trying to build a levitron, decided to use hall switch for sensing the distance of the lifted object. TLE4945L was the only one I was able to obtain.
I wasn't able to find much about hall effect sensors online, and there is one thing that bothers me.
It works fine when I bring the south pole of the magnet to it, the led lights on, but when I move it away, it won't turn off. It only turns off I bring the north pole close to it.

Why is it so? Cause if it's gonna work like that, I won't be able to sense when it starts falling down.
Also, if I attach it to the bottom of my electromagnet, with it's "back" near it, will the electromagnet also effect it somehow?
