Product Description

  • 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!
  • When water flows through, the internal rotor will change its speed with different rates of flow, and the hall effect sensor outputs the corresponding pulse signal.
  • Use with laser cutters or CNC to measure if and how much water is flowing through a laser tube or CNC spindle for cooling.
