Connect the sensor's yellow signal wire directly to Digital Pin 2 of the Arduino Uno. Pin 2 supports external interrupts ( INT0 ), which are necessary for precise pulse counting.
: Connect the RS, Enable, and Data pins (D4-D7) of the LM016L LCD to Arduino digital pins (e.g., Pins 12, 11, 5, 4, 3, 2) or use an I2C adapter to save pins.
After installation, open the component picker, locate your YFS201 part, and place it in a test schematic. Connect its output to a microcontroller pin and write a simple interrupt‑based pulse‑counting routine. Vary the flow rate (by changing a parameter or an external voltage) and verify that the computed flow rate matches the expected value. yfs201 proteus library
By following this guide, you can successfully integrate the into your design, paving the way for accurate and functional water monitoring applications.
The library isn’t official from Labcenter. You can find it on: Connect the sensor's yellow signal wire directly to

: Obtain the YF-S201 Proteus library (often available on sites like The Engineering Projects Copy Files : Copy the library files from your download folder. Paste in Proteus : Navigate to the Proteus installation folder (e.g., After installation, open the component picker, locate your
If you try to place a component that lacks a valid .LIB‑.IDX pair, Proteus will display errors such as “component not found”, “unknown model”, or “device cannot be placed”.
