Yfs201 Proteus Library Exclusive 〈Real〉

Connect the pins as follows:

Upload your firmware to the virtual microcontroller. A standard interrupt-based pulse counting code works perfectly here.

// Example logic for the simulation
volatile int pulseCount = 0;
float flowRate = 0.0;
void setup() 
Serial.begin(9600);
attachInterrupt(0, pulseCounter, RISING); // Digital Pin 2

void loop() 
// Calculate flow rate based on pulse count
// YFS201 Factor: 7.5 * pulseCount (approx)
flowRate = (pulseCount / 7.5);
Serial.print("Flow Rate: ");
Serial.print(flowRate);
Serial.println(" L/min");
pulseCount = 0;
delay(1000);

void pulseCounter() 
pulseCount++;

During the simulation run, you can pause the simulation, edit the "Flow Rate" property of the YFS201 model to "10 L/min", resume, and instantly see the Serial Monitor update to reflect that flow.

The availability of an exclusive YFS201 library is more than just a convenience; it represents a shift in Hardware-in-the-Loop (HIL) simulation capabilities.
