Effect Hall Sensor


I will register the variation of the distance between a magnet and an hall effect sensor (I would like to measure the brakes intensity of my bike, so my project is to put the magnet on bike's brake handle and the sensor somewhere in the bike's handlebar; and to use Arduino for converting and recording this). I've been recently studying the types of sensors (digital and analog), but I am a beginner in this topic. It seems that, in my case, an analog hall effect sensor will be more appropriated than a digital one. Can anyone who has worked with an hall effect sensor give me any advice?
