Water flow sensor measures the rate of liquid flowing through it. Consists of a plastic valve body, flow rotor and hall effect sensor. Usually placed at the inlet end. 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. Can be used with a microcontroller such as Arduino to monitor devices such as a coffee maker, sprinkler or anything else. Operates on 5vdc @ 15mA. Water flow range 0.3-6 L /min. Water pressure <0.8MPa. 4mm I.D. x 6mm O.D. inlets. Overall dimensions 35mm x 35mm x 26mm. 6" 3-wire leads with 3-pin connector.
