Proteus Library ((exclusive)) - Yf-s201

Open Proteus. In the window (press the "P" key), type YF-S201 or YFS201 in the search bar. The component should appear. If it doesn’t, double-check the folder path and file integrity.

The is a widely used Hall-effect water flow sensor in DIY and industrial projects for measuring liquid volume and flow rate . While Proteus does not include it in its default component library, third-party libraries like the New YF-S201 Flow Sensor Library from Electronics Tree allow you to simulate it without a "wet lab" setup. Key Features of the YF-S201 Library

Wrong folder (e.g., using USERLIB instead of LIBRARY ) or Proteus version mismatch. Fix: Ensure you placed files in DATA\LIBRARY , not DATA\USERLIB . For Proteus 9+, use ProgramData path. Restart Proteus as admin.

Recommendation: Stick to Method 1 for reliable results. yf-s201 proteus library

You cannot vary the flow rate during simulation. It mimics a constant, steady flow only.

If your library model features a test pin, connect the middle wiper of the POT-HG potentiometer to it. Connect the other two ends of the potentiometer to +5V and Ground. Turning this knob during the simulation will mimic changing water speeds. Step 3: Wiring the LCD

The YF-S201 sensor typically consists of a plastic valve body, a water rotor, and a Hall-effect sensor. Open Proteus

Look at the bottom output console of the Arduino IDE. Find the file path ending in .hex (e.g., C:\Users\Name\AppData\Local\Temp\build...\sketch.ino.hex ). Copy this path.

The is arguably the most popular water flow sensor among hobbyists, students, and engineers working on Arduino, ESP32, or STM32 projects. It is inexpensive, reasonably accurate, and easy to interface. However, when moving from physical prototyping to simulation, many developers hit a wall.

Simulating water flow accurately in Proteus requires tricking the Arduino into reading pulses, as actual water will not be moving in the simulation.

Click on the LOGICSTATE component to toggle it between High and Low (1 and 0). Every toggle counts as a pulse for your Arduino.
