The 'hall effect" is the name for a magnetic pulses impact on current flow.All magnetic switches work on this principal.The beauty of it is precision,you can accurately measure shaft position at any speed,its why electronic based ignition systems work so well.As an old fossil I dont care for 0 to 5v controlling my destiny,I prefer gears and breaker switches..as an old mechanic I love plugging in a box,pulling a code and changing a part,it gets you home faster
