Proteus supports the creation of custom simulation models using the C++ programming language. You would use the Proteus VSM (Virtual System Modelling) SDK to create a DLL (Dynamic Link Library) that defines the sensor's electrical behavior, pinout, and the frequency-to-flow calculations. While powerful, this path is generally reserved for professional embedded systems engineers.
Optional: Connect a 10kΩ pull-up resistor between the signal pin and +5V. yf-s201 proteus library
Typical path for newer versions: C:\ProgramData\Labcenter Electronics\Proteus 8 Professional\Data\LIBRARY (Note: ProgramData is a hidden folder by default in Windows). Proteus supports the creation of custom simulation models
