Before diving into the library, we must understand the hardware.
Obtain the .LIB and .IDX files for the YFS201 sensor.
Most engineers rely on physical prototyping for flow sensors because the standard Proteus component library lacks a dedicated simulation model for the YFS201. This leads to wasted time, burnt components, and iterative guesswork. yfs201 proteus library exclusive
(L/min), it provides reasonable accuracy for many applications, though it may require calibration for precision tasks. Why Use the "YFS201 Proteus Library Exclusive"?

The speed of the rotor changes with different rates of flow. The Hall-effect sensor outputs a corresponding high/low digital pulse signal (square wave). Pin Configuration: The sensor uses three simple wires: Red (VCC): 5V to 24V DC power supply. Black (GND): Ground connection. Yellow (Pulse/Data): PWM pulse output signal.

Connect the sensor’s Signal wire to an interrupt-capable pin (e.g., Pin 2) on the Arduino.
