Yfs201 Proteus Library Today

Build an astable multivibrator using a 555 timer and a potentiometer. Adjusting the pot changes the frequency sent to the MCU. This is an excellent analog hardware simulation of the YFS201.

Yes. Add multiple instances; rename signal pins to avoid interrupt conflicts in code.

If you cannot find a YFS201 library, use these Proteus substitutes: yfs201 proteus library

Proteus allows custom DLLs (VSM models) in C++. Advanced users can model YFS201 behavior with parameters like min flow, max frequency, and duty cycle.

For power users, Proteus + YFS201 library can be integrated with: Build an astable multivibrator using a 555 timer

Example advanced simulation scenario:

You can create your own:

If you want it to look like a flow sensor on the schematic:
