The hall-effect sensor outputs the corresponding pulse signals
Detects flow in water dispenser or coffee machine
The Elecrow 1/2-In Water Flow Sensor consists of a magnetic core, rotating impeller, external casing and sensor, and a hall-effect sensor.
When water flows through the rotor, rotor rolls, it activates the magnetic core to trigger switch action speed changes with different rate of flow. The hall-effect sensor outputs the corresponding pulse signals, users can get the flow speed via detecting the pulse. It is suitable to detect flow in water dispenser or coffee machine.
Great little water flow sensor. Code is rotten but it is easy to write something better. I wrote a simple RPS routine and then measured flow to find a scaling factor. Works great!
