Yf-s201 Proteus Library -

// Frequency = pulses per second // YF-S201: Flow rate (L/min) = (Frequency / 7.5) flowRate = (pulseCount / 7.5); totalLiters += (flowRate / 60); // Cumulative volume

Connect the Yellow signal wire (or your Pulse Generator output) to Digital Pin 2 or Digital Pin 3 on the Arduino. These pins support hardware interrupts ( INT0 and INT1 ), which are crucial for tracking rapid sensor pulses without lagging the CPU. yf-s201 proteus library

void loop() unsigned long currentMillis = millis(); // Frequency = pulses per second // YF-S201:

Place the PULSE generator tool from the Left Generator Toolbar. Connect its positive terminal to Digital Pin 2 of the Arduino. Pin 2 supports external hardware interrupts ( INT0 ), which are necessary for accurate pulse tracking. Connect its positive terminal to Digital Pin 2

: The Hall-effect sensor outputs a digital square wave pulse. The frequency of these pulses is directly proportional to the velocity of the liquid. Technical Specifications Working Voltage : 5V to 18V DC Maximum Current : 15 mA (at 5V DC) Flow Rate Range : 1 to 30 Liters per Minute (L/min) Output Signal : 5V TTL digital pulse Pulse Frequency Formula : is frequency in Hz, and is flow rate in L/min) Why Do You Need a Third-Party Proteus Library?
