While Proteus has a massive component library, it often lacks specific, pre-calibrated models for niche sensors like the YFS201. Without a proper model, you cannot accurately simulate how your microcontroller (Arduino, PIC, STM32) will read the pulse data. 1. Accurate Pulse Generation yfs201 proteus library exclusive
