At its heart, the YF‑S201 works on the Hall‑effect principle. Inside the sensor sits a turbine wheel fitted with a magnet. As water flows through the sensor, the turbine spins, causing the magnet to repeatedly pass by a Hall‑effect sensor. This movement generates a clean, square‑wave pulse signal: the faster the flow, the higher the pulse frequency. By counting those pulses over time, you can compute both the instantaneous flow rate (in litres per minute) and the total volume of water that has passed through the sensor. yfs201 proteus library
