Water Flow Measurement Sensor Pinout:
The water flow measurement sensor (YF-S201) with high-grade quality sealing property. It works on the Hall effect principle and with a flow rate range of 1~30L/min and allowing pressure of ≤1.75MPa.

The module has three pins:
1. Power.
2. Ground
3. Analog output.

Features Water Flow Measurement Sensor:
1. Operating Voltage: 4.5V to 18V DC
2. Output type: 5V TTL
3. Maximum current draw: 15mA at 5V
4. The sensor used: Hall Effect
5. Working Flow rate: 1 to 30 Liters/Minute
6. Accuracy: ±10%
7. Pulses per Liter: 450
8. Output duty cycle: 50% +-10%
9. Maximum water pressure: 2.0 MPa
10. Flow rate pulse characteristics: Frequency (Hz) = 7.5 * Flow rate (L/min)
