About this product
The YF-S201C is a transparent water flow sensor that measures flow rate with a Hall-effect sensor and a rotor. Each rotation produces pulses that a microcontroller counts to calculate flow, which suits DIY water monitoring and industrial flow projects. The transparent body lets you see the rotor turning.

How do I wire it to a microcontroller?
Connect the red wire to the supply (5V is common), the black wire to GND, and the yellow signal wire to a pin that supports interrupts. Make sure the sensor and microcontroller share a common ground.
How do I convert the pulses into a flow rate?
Count the pulses over a fixed time interval, then divide by the pulses-per-litre factor. For the YF-S201 family this factor is commonly quoted as about 450 pulses per litre, but calibrate with a known volume because the value varies between units.
