If you cannot find a reliable library file or prefer not to install third-party files, you can simulate the of the YFS201 using standard Proteus components. This is a vital skill for any engineer.
By following this guide, you can simulate complete water flow monitoring systems, debug interrupt-driven code, and visualize flow rates on virtual LCDs—all before ordering a single component. yfs201 proteus library
