Water Flow Sensor 1-30L/min 2.0MPa YF-S201

Water Flow Sensor 1-30L/min 2.0MPa YF-S201

The YF-S201 water sensor is a cost-effective and reliable device designed to measure the flow rate and volume of fluids in pipelines. It features a durable copper body with an internal water rotor and a Hall effect sensor. The Hall sensor detects changes in magnetic flux as the rotor spins, generating a pulse output with each revolution. With its simple 3-wire interface and compatibility with microcontrollers, it's ideal for DIY projects, automation systems, and basic fluid measurement tasks.

Features:

  1. Flow Measurement Technology: Designed for in-line fluid flow rate and volume measurements using a copper body and internal rotor system.
  2. Hall Effect Sensor: Integrated magnetic Hall effect sensor provides a pulse signal output for each rotor spin; safely sealed from the water path.
  3. Three-Wire Configuration: Simple wiring – Red (5-24VDC Power), Black (Ground), Yellow (Pulse Output).
  4. Rotor-Magnet Interaction: Flowing water rotates a magnetic rotor, with the Hall sensor detecting rotor speed to produce pulse output.
  5. Square Wave Pulse Output: Generates TTL-level pulse signals; frequency proportional to flow rate (Hz ÷ 7.5 = L/min).
  6. Microcontroller Compatible: Easily interfaces with Arduino, Raspberry Pi, and other MCU platforms for logging and automation.
  7. Basic Calibration: Requires calibration to achieve better than 10% accuracy due to variation from pressure and orientation.
  8. Durable Build: Designed for 300,000+ operational cycles under standard conditions.
