Description of the YF-S201 YF-S201 is a water flow measurement sensor with high-grade quality sealing property. It works on the Hall effect principle and with a flow rate range of 1~30L/min. The module has three pins: Power, Ground, and the Analog output. YF-S201 consumes very little current and can work with an allowing pressure of ≤1.75MPa. Features of YF – S201 Operating Voltage: 4.5V to 18V DC Output type: 5V TTL Maximum current draw: 15mA at 5V The sensor used: Hall Effect Working Flow rate: 1 to 30 Liters/Minute Accuracy: ±10% Pulses per Liter: 450 Output duty cycle: 50% +-10% Maximum water pressure: 2.0 MPa Flow rate pulse characteristics: Frequency (Hz) = 7.5 * Flow rate (L/min ) Outer diameter: 20mm Intake diameter: 9mm Outlet diameter: 12mm Pin configuration of YF-S201 YF – S201 has 3 Pins for power and the output. The table below explains the color, pin type, and function of the pin.
