## Overview

The ZIYUN Water Flow Sensor (1/2") is a high-performance device designed for precise measurement of liquid flow rates. With a robust plastic construction, it features a flow rotor and hall effect sensor, ensuring accuracy and reliability in various applications. Capable of measuring flow rates from 1 to 30 L/min and with a proof water pressure of less than 1.75 Mpa, this sensor is perfect for Arduino enthusiasts looking to enhance their projects.

## Description

The Gravity Water Flow sensor measures the rate of a liquid flowing through it.The YF-S201 water flow sensor consists of a plastic valve body, flow rotor and hall effect sensor. It is usually used at the inlet end to detect the amount of flow.When liquid flows through the sensor, a magnetic rotor will rotate and the rate of rotation will vary with the rate of flow. The hall effect sensor will then output a pulse width signal. Connect it to a microcontroller and you can monitor multiple devices such as your coffee maker, sprinkler or anything else, and control the water flow rate to suit your needs!The Gravity interface make it be compatible with Arduino IO Expansion Shield.Note: *A 20 mm rifled pipe is recommended *Avoid unit contact with corrosive chemicals *The unit must be installed vertically, tilted no more than 5 degrees *Liquid temperature should be less than 120 C to avoid damage to unitSPECIFICATION Inner Diameter: 11 mm Outside diameter: 20 mm Proof Water Pressure: <1.75 MPa Water Flow Range: 1-30 L/min Voltage Range: 3.5 to 12 V Operating Current: 15 mA (DC 5V) Insulation Resistance: >100 Megger ohm Accuracy: ±5% (2 to 30L/min) The Output Pulse High Level: >4.7 VDC (DC input voltage 5 V) The Output Pulse Low Level: <0.5 VDC (DC input voltage 5 V) Output Pulse Duty Ratio: 50% ± 10% Water-flow Formula: 1L = 450 square waves Working Humidity Range: 25% ~ 95% RH (no frost) Dimension: 62*36*35 mm/2.44*1.37*1.37 inches Weight: 52gPACK LIST Gravity - Water Flow Sensor - 1/2" *1
