Cool applications (JOYSTICK) with a 3D Magnet Sensor!

With a 3D magnet sensor that costs $1 and a 15 cent magnet we are able to measure water flow rate, joystick movement, linear slide position and position of a knob.

The sensor can detect the position and movement of a magnet in 3D space. It does this with 3 internal hall effect probes, one along each axis of the sensor. The hall probes measure magnetic flux density. This means if a magnet is attached to a slider, ball and socket or rotary shaft the position and movement of those mechanical components can be known in a system. A 3D magnetic sensor provides a contactless position sensing alternative to applications which traditionally use mechanical or optical solutions.The most common being a potentiometer.

Advantages:
contactless sensing
cost sensitive
not sensitive to dirt
tactile feeling can designed by mechanical interface
higher range of motion compared to linear hall solution
positioning between sensor and sliding interface is very flexible
enables pass by configurations
