Water Flow Sensor YF-S401 Flowmeter 0.3-6L/min 2mm White

The Water Flow sensor measures the rate of a liquid flowing through it. The YF-S401 water flow
sensor consists of a plastic valve body, flow rotor, and hall effect sensor. It is usually used at the inlet
end to detect the amount of flow. When liquid flows through the sensor, a magnetic rotor will rotate
and the rate of rotation will vary with the rate of flow. The hall effect sensor will then output a pulse
width signal. Connect it to a microcontroller and you can monitor multiple devices such as your
coffee maker, sprinkler, or anything else, and control the water flow rate to suit your needs!
