Gravity: Digital Hall Sensor

What's the best way to detect the magnet? Use anther magnet. But it's not sensitive enough. You have to feel it by yourself. This Hall sensor knows whether there is a magnetic object nearby or not, and it correctly tells you through a digital output.
Note: It's a omnipolar magnet dectector so that it can not tell two polarities apart.
