Gravity: Digital Water Flow Sensor For Arduino - 1/8"; SF_Power Supply Our Smallest Arduino-Compatible Board YetThe 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
