3.5-24V DC Water Flow Sensor YF-S201 Flowmeter With 1-30 Liters Per Minute Range And 1.75 MPa Rating, Liquid Flow Switch For DIY Projects, Plug And Play Install With Filter Screen, Accurate Water Flow Monitoring

3.5-24V DC Water Flow Sensor, 1-30 L/min, 1.75 MPa
✔️ 1-30 L/min flow range, 3.5-24V DC operation, G1/2 thread, 1.75 MPa rating

This compact, plug-and-play water flow sensor is designed for DIY electronics and small fluid pipelines. Ideal for hobby projects, irrigation setups, aquariums, and cooling loops, it provides a simple way to monitor liquid flow with a microcontroller-friendly pulse output. A filter screen should be installed at the inlet to prevent debris from reaching the sensor, and installation should be indoors and out of extreme vibration to maintain accuracy. Pack includes 1 sensor unit.
