is a pulse-output sensor, specific simulation models are often bundled in "Sensor Libraries" for Proteus. Search for:

To use the YF-S201 in Proteus, you must manually add the library files to your software directory: Download Files : Obtain the library zip containing WaterSensorTEP.IDX WaterSensorTEP.LIB WaterSensorTEP.HEX Locate Folder : Navigate to the Proteus installation path, typically:

After extensive research, I've identified the most reliable sources for obtaining a YFS201 simulation model for Proteus. Let me share what I've found so far.

// Update total volume totalVolume += flowRate / 60.0; // L/s × 1s = L

If you're interested in learning more or contributing to the project, you can find the library on:

by comparing simulation outputs against real sensor specifications

Check your digital wiring layout. Ensure the RS and Enable pins are not swapped.

Using the , you can simulate real-world water flow rates directly in Proteus VSM . ⚙️ How the YF-S201 Water Flow Sensor Works
