Introduction

YF‑S201 is a Hall‑effect water flow sensor with G1/2(1/2 inch) threaded interface. It detects water flow speed by internal turbine rotor and outputs pulse signal. The pulse frequency corresponds to water flow volume. Support flow range 1‑30L/min. It can work with Arduino and other microcontrollers. Widely applied in water heater, water dispenser, water vending machine and various water flow monitoring DIY systems.
