Yfs201 Proteus Library Jun 2026
Simulating hardware designs before prototyping saves time, reduces component damage, and speeds up firmware development. The YF-S201 is a highly popular, hall-effect-based water flow sensor used extensively in Arduino and microcontroller projects.
Open the properties of your YF-S201 library component (or your manual Pulse Generator). Set a fixed pulse frequency.
Copy and paste these two files into your Proteus library directory:
void loop() unsigned long currentTime = millis(); if (currentTime - lastTime >= 1000) // calculate every second detachInterrupt(digitalPinToInterrupt(2)); // frequency = pulseCount in one second float frequency = pulseCount; // pulses per second = Hz flowRate = frequency / 7.5; // L/min totalVolume += flowRate / 60.0; // integrate volume (litres) yfs201 proteus library
4.5V to 18V DC (typically 5V for microcontrollers). Accuracy: (can be calibrated for better precision). Pulse Characteristic: is frequency in Hz and is flow rate in L/min). Pulses per Liter: Approximately 450 pulses. 2. Proteus Library Installation
What are you pairing with the sensor (Arduino, PIC, ESP32)? Do you need assistance creating the LCD display circuitry ?
If you cannot find a YFS201 library, use these Proteus substitutes: Set a fixed pulse frequency
in Proteus that outputs a pulse train (such as a pulse generator or signal source)
Modify code:
is not in your default Proteus component list, follow these steps to add it manually: How to Add the ESP32 Library to Proteus 8 Pulse Characteristic: is frequency in Hz and is

Installation Steps Locate Proteus Folders: Right-click your Proteus shortcut and select Open File Location Find the 'LIBRARY' Folder: Usually located in
: If your LCD remains completely blank during simulation, ensure that you successfully copied the compiled project's .hex path link directly into the Arduino component properties window inside Proteus.
Simulating the YFS201 in Proteus offers several advantages:
// The math: (Pulse Count / 7.5) = L/min flowRate = ((1000.0 / (millis() - oldTime)) * pulseCount) / 7.5;
: Go to your Proteus installation directory. This is typically found at:
