Arduino Water liquid flow sensor probe Pulse Output 1-30 L/min 1/2" inner diameter 20mm hose recommended | Инструменты

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!

The Gravity interface make it be compatible with Arduino IO Expansion Shield.

Note:
*A 20 mm hose is recommended
*Avoid unit contact with corrosive chemicals
*The unit must be installed vertically, tilted no more than 5 degrees
*Liquid temperature should be less than 120 C to avoid damage to unit
