If you search for YF-S201 in the Proteus window, you will not find it. Proteus lacks a native simulation model for this sensor because it is a physical electromechanical device (a turbine with a Hall effect sensor).
: You can test the sensor with different microcontrollers (like Arduino Uno or Raspberry Pi ) to ensure your voltage dividers or pull-up resistors are correctly configured for the 5V to 18V operating range. How to Use the Library Flow sensor YF-S201 - General Guidance - Arduino Forum
Switch to Proteus, double-click your Arduino component, and paste the .hex path into the property field. Click OK . Running and Testing the Simulation
If you search for "YF-S201" in the Proteus Component Library search bar, you will likely find zero results. This is because the Proteus developers generally do not include specific breakout boards or hobbyist sensors in the default install.
Test the formula for converting pulses to Liters per Minute (L/min) or Total Volume.
Optional: Connect a 10kΩ pull-up resistor between the signal pin and +5V.
Example Arduino test (summary)
Add the ARDUINO UNO board (requires the Arduino Proteus library) to your workspace.
In Proteus, right-click the Arduino board -> . Load the compiled .hex file. Run the simulation.
