Water Flow Sensor / Liquid Flowmeter YF-S201 with Hall Effect (1-30 L/min)

The compact YF-S201 water flow sensor is designed to measure flow rate and totalize the volume of liquid flowing through various piping systems. It works by detecting the rotation of an internal impeller with an integrated magnet driven by the water flow; the Hall effect sensor picks up this rotation and outputs it as a pulse signal. The housing is made of durable plastic and fitted with standard threaded fittings for easy installation in the main line. It is a popular solution for smart home systems, automatic irrigation, and water consumption monitoring. Features: Product type: water flow sensor / flowmeter (Water Flow Sensor) Specifications: model YF-S201, working flow range 1 to 30 L/min, maximum working pressure up to 1.75 MPa, plastic housing with threaded fittings, 3-wire interface cable Purpose: flow rate measurement and precise volume metering of flowing liquid in water supply systems, automatic irrigation, and DIY projects
