YF-S201 Water Flow Sensor 1–30 L/min White - Hall Effect Pulse Output
The YF-S201 is a Hall-effect-based inline water flow sensor compatible with 5V/3.3V logic systems like Arduino and Raspberry Pi. It provides a pulse output proportional to flow rate, suitable for monitoring water consumption in projects ranging from irrigation to simple fluid dispensing.
Features
- Hall Effect sensor outputs a digital pulse for each revolution of the internal pinwheel.
- Flow rate range from 1 to 30 liters per minute with a maximum pressure rating of 2.0 MPa.
- Wide operating voltage from 5V to 18V DC with low 15mA current consumption.
- Features 1/2″ NPT pipe threads for easy inline installation in water lines.
- Pulse output frequency scales linearly at approximately 7.5 Hz per L/min.

The YF-S201 water flow sensor employs a mechanical pinwheel and a sealed magnetic Hall effect sensor to generate a digital pulse signal corresponding to fluid flow. Each pulse represents a specific volume, enabling flow rate calculation through simple frequency measurement on a microcontroller’s digital input pin.
Constructed with brass fittings and a sealed sensor compartment, it is designed for durability in water applications within its specified temperature and pressure limits. While not a precision instrument, it provides reliable flow indication for basic monitoring and control tasks in DIY electronics, aquaponics, and simple industrial setups.
