Beginners often waste hours searching for a .LIB or .IDX file to import. While third-party libraries exist on the internet, they are often buggy or contain malware. Fortunately, The Solution: Build a Virtual Model Since the YF-S201 is essentially a Hall Effect sensor generating pulses, you can simulate it in Proteus using two methods: the Digital Clock Method (easiest) or the Potentiometer + ADC Method (mimics hardware circuits). Method 1: The Digital Clock (Frequency Generator) This is the most accurate way to simulate the sensor's digital output. Since the sensor outputs a frequency, we can use a digital clock source to mimic the pulses. Catia V5 R21 Download Torrent Top ★
The YF-S201 is one of the most popular water flow sensors among hobbyists and engineering students. It is commonly used in projects involving water measurement, automatic dispensers, and smart irrigation systems. However, when it comes to simulation in Proteus ISIS , many users hit a wall.
void loop() { if ((millis() - oldTime) > 1000) { // Only process once per second // Disable interrupt briefly for calculation detachInterrupt(digitalPinToInterrupt(2)); // Formula: Frequency / 7.5 = L/min flowRate = ((1000.0 / (millis() - oldTime)) * pulseCount) / 7.5; oldTime = millis(); flowMilliLitres = (flowRate / 60) * 1000; totalMilliLitres += flowMilliLitres; Serial.print("Flow rate: "); Serial.print(flowRate); Serial.print(" L/min\tOutput Frequency: "); Serial.print(pulseCount); Serial.println(" Hz"); pulseCount = 0; attachInterrupt(digitalPinToInterrupt(2), pulseCounter, RISING); } }
// YF-S201 Simulation Code for Proteus // Connect DCLOCK to Digital Pin 2 (INT0)
volatile int pulseCount = 0; float flowRate = 0.0; unsigned int flowMilliLitres = 0; unsigned long totalMilliLitres = 0; unsigned long oldTime = 0;
