The water flow sensor consists of a plastic valve from which water can pass. A water rotor along with a Hall Effect sensor is present the sense and measure the water flow. When water flows through the valve it rotates the rotor. ... This change is calculated as output as a pulse signal by the Hall Effect sensor.
- The simple and compact module.
- Easy to Install.
- High Sealing Performance.
- High-Quality Hall Effect Sensor.

This is YF-S201 Water Flow Measurement Sensor with 1-30Leter/min Flow Rate in black color. This sensor sits in line with your water line and contains a pinwheel sensor to measure how much liquid has moved through it. There’s an integrated magnetic Hall Effect sensor that outputs an electrical pulse with every revolution. The Hall Effect sensor is sealed from the water pipe and allows the sensor to stay safe and dry.
By counting the pulses from the output of the sensor, you can easily calculate water flow. Each pulse is approximately 2.25 milliliters.
Note - This isn’t a precision sensor, and the pulse rate does vary a bit depending on the flow rate, fluid pressure, and sensor orientation. It will need careful calibration if better than 10% precision is required. However, it’s great for basic measurement tasks!
good for making water motor. nice product.
As mentioned it's easy and a compact product. delivered as expected.
Useful sensor for hobby projects. But quite pricey on Amazon
