Yf-s201 Proteus Library < 480p HD >

Use this if you only need the physical footprint for PCB design.

The sensor outputs a continuous stream of digital high/low pulses (a square wave) via its yellow signal wire.

// YF-S201 Simulation Code for Proteus // Connect DCLOCK to Digital Pin 2 (INT0)

The YF-S201 is an inline, mechanical fluid flow sensor consisting of three primary elements: a plastic valve body, a magnetic pinwheel rotor, and a Hall Effect integrated circuit. yf-s201 proteus library

For standard YF-S201 sensors, the output frequency formula is approximately , where is the pulse frequency (Hz) and is the flow rate in liters per minute (L/min). How to Install the YF-S201 Proteus Library

For realistic simulation (e.g., flow starts, stops, ramps up):

Place a Pulse Generator block to simulate the yellow signal wire of the YF-S201. Connect this generator directly to digital Pin 2 (External Interrupt 0) on the Arduino. Pull-Up Resistor Configuration: Connect a resistor between the Pin 2 signal line and the Use this if you only need the physical

Serial.print("Flow Rate: "); Serial.print(flowRate); Serial.println(" liters per minute");

This article serves as a complete resource. We will explore why the library is missing, how to simulate the YF-S201 without a perfect model, and—for advanced users—how to create your own custom Proteus library for the sensor.

Since the YF-S201 is essentially a Hall Effect sensor generating pulses, you can simulate it in Proteus using two methods: the (easiest) or the Potentiometer + ADC Method (mimics hardware circuits). For standard YF-S201 sensors, the output frequency formula

Compile the Arduino code above. Go to in the Arduino IDE to generate the .hex file. Double-click the Arduino Uno component inside Proteus.
