Seeed 114991172 Grove - Water Flow Sensor YF-B2

Seeed 114991172 Grove - Water Flow Sensor YF-B2 Water flow sensor consists of a copper body, a water rotor, and a hall-effect sensor.

When water flows through the rotor, the rotor rolls and its speed changes with different rate of flow. The hall-effect sensor outputs the corresponding pulse signal. This one is suitable to detect flow in water dispenser or coffee machine.
