This paper presents the usage of Hall-Effect sensors for the creation of a low cost, zero friction, minimally invasive precise positional sensor. Hall-Effect sensors are generally being used for revealing the speed of geared-wheels as well as the angular position of wheels having an array of magnets mounted on. In most cases the Hall-Effect sensor have only been used as threshold sensing devices for revealing the presence of magnetic field.
