After two Hall switches, our final click board for this week is LIN HALL click, which is a linear Hall sensor.
LIN HALL click will give you an output linearly proportional to the density of the magnetic flux it’s exposed too.
Plug LIN HALL click to your nearest mikroBUS™ socket, use the Libstock example provided, then take a fridge magnet and watch as the values go up and down as you move it closer or farther from the onboard MLX90242 linear Hall sensor IC.
A north pole magnet field will increase the output, while a south pole field decreases it.
In applications more practical than fiddling with fridge magnets, linear Hall sensors are used to infer the linear or rotary position of a target object (as long as there is a magnet attached, or something to disturb an existing magnetic field). Examples include measuring the position of throttle valves, or the movements of a joystick.
The late Edwin Hall would be pleased.
