Water flow Sensor – YFS201

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

Technical Specifications

Parameter Specification
Model YFS201
Type Hall effect turbine
Connection 1/2″ BSP
Flow Range 1-30 L/min
Pulse Rate ~450 pulses/L
Operating Voltage 5V
Interface Digital pulse
Accuracy ±10%

Applications

  • Water flow monitoring
  • Consumption tracking
  • Leak detection
  • Smart irrigation
  • Industrial flow monitoring

Important Notes

  • 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
