YF-S201 Water Flow Measurement Sensor — 1–30 L/min cable or maintain a stable voltageYF S201 Water Flow Measurement Sensor 1 to 30 L min The YF S201 is a compact Hall effect based water flow sensor that measures the volume of liquid passing through a pipe. As water flows, a rotor spins and the built in Hall effect sensor generates pulses proportional to the flow rate. Connect it to an Arduino or ESP32 to build smart water meters, irrigation controllers, or leak detection systems with ease. Technical Specifications Parameter Value
