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!

Note:
*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

  • Imagine getting home from work, its winter, its cold. You have a shower to warm up and half way through your shower...... your water stops. You wrap a towel around yourself, remove the shampoo from your eyes and go out into the cold to swap the tanks as the water tank you were using had run dry. This was a common occurrence in my house......... but not anymore. Now I can keep visually see the level of water in my water tanks on m...
