Introduction

The Water Flow sensor measures the rate of a liquid flowing through it. The YF-S201 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!

 A 20 mm rifled pipe 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
