pulseCount = 0; lastTime = currentTime; attachInterrupt(digitalPinToInterrupt(2), pulseCounter, RISING);

No matter which path you choose, the key insight remains the same: . Simulate the frequency, and you simulate the sensor.

volatile int pulseCount; const int sensorPin = 2; // Pulse Output connected here float flowRate; unsigned int flowMilliLitres; unsigned long totalMilliLitres; void IRAM_ATTR pulseCounter() pulseCount++; void setup() Serial.begin(9600); pinMode(sensorPin, INPUT_PULLUP); pulseCount = 0; flowRate = 0.0; totalMilliLitres = 0; attachInterrupt(digitalPinToInterrupt(sensorPin), pulseCounter, FALLING); void loop() // Calculate flow every second static unsigned long oldTime = 0; if ((millis() - oldTime) > 1000) detachInterrupt(digitalPinToInterrupt(sensorPin)); // YF-S201 formula: Frequency (Hz) / 7.5 = Flow Rate (L/min) flowRate = ((1000.0 / (millis() - oldTime)) * pulseCount) / 7.5; oldTime = millis(); totalMilliLitres += (flowRate / 60) * 1000; Serial.print("Flow Rate: "); Serial.print(flowRate); Serial.print(" L/min"); Serial.print(" Total Volume: "); Serial.print(totalMilliLitres); Serial.println(" mL"); pulseCount = 0; attachInterrupt(digitalPinToInterrupt(sensorPin), pulseCounter, FALLING); Use code with caution. Key Tips for Success

: Locate and download the library files (usually .LIB and .IDX files) from specialized community sources like The Engineering Projects or GitHub .

is one of the most popular, cost-effective water flow sensors, but designing circuits with it requires precise simulation before physical assembly.

Here is the code to interpret the data from the simulated sensor:
