void loop() if(millis() - oldTime > 1000) //every 1 second detachInterrupt(0); flowRate = (pulseCount / 7.5); // Liters per minute lcd.setCursor(0,0); lcd.print("Flow: "); lcd.print(flowRate); lcd.print(" L/min "); pulseCount = 0; oldTime = millis(); attachInterrupt(digitalPinToInterrupt(2), pulseCounter, RISING);

The sensor outputs a pulse signal (square wave) where the frequency is directly proportional to the flow rate.

Custom library packages typically arrive inside a .zip or .rar archive. Extract the folder to find two essential files: _YourLibraryName_.IDX (Index file) _YourLibraryName_.LIB (Library file) Step 2: Locate Your Proteus Library Directory

In real life, the YFS201 outputs a digital pulse train proportional to flow. But in Proteus, without a model, you cannot test your interrupt-driven code or LCD counter. You either wait for hardware or fake it with a signal generator. The solves this by embedding the physics into a virtual component.

YFS201Model.LIB (Component graphical and behavior model file) Step 2: Copy to Proteus Directories

By adjusting the "Pulse per Liter" property (which is editable in the exclusive version) from 450 to 8100, you simulate high-precision fuel metering.

The is an indispensable tool for engineers and hobbyists creating fluid measurement systems. By bridging the gap between theoretical code and physical behavior, this library ensures that your projects work correctly the first time.
