@Ducky, I'm not sure you want to go for a 'switchy' Hall Effect sensor... you will end up with practically the same behavior as with the IR proximity sensor. There are various Hall Effect sensors. Of course, the most used ones are the switching ones. They have usually Schmitt Trigger behavior / built in, and some they go even further and require a polarity change to switch to the other state. Therefore, you have to find a Hall Effect sensor that just measures the intensity of the magnetic field (see this intro]). You need something like Honewell SS49/SS19 Series with 5v, GND, and Hall Voltage out. Hall Voltage is related to the intensity of the magnetic field.
