01 — About

What it does

The YFS201 Water Flow Sensor uses a Hall effect sensor to measure water flow rate. As water flows through, it spins an internal rotor whose speed is proportional to flow rate, providing digital pulse output.

Key features

  • Hall effect flow sensing
  • Digital pulse output
  • 1/2-inch BSP thread
  • 1-30 L/min range
  • ~450 pulses per liter
  • 5V operation
  • Compact design

Good to know

  • Install with flow direction arrow pointing correctly
  • Count pulses and divide by calibration factor for liters
  • Use interrupt pin for accurate pulse counting
  • Minimum flow rate required for reliable readings
  • May need debouncing for clean pulse counting
