Yfs201 Proteus: Library

using a generic pulse generator, a dedicated offers significant advantages:

Copy the YFS201.LIB and YFS201.IDX files into the LIBRARY folder.

Instead of looking for a flow sensor part, use a or a Pulse Source .

void setup() pinMode(2, INPUT_PULLUP); attachInterrupt(digitalPinToInterrupt(2), pulseCounter, RISING); lcd.begin(16, 2); lcd.print("Flow Meter Ready"); delay(2000); lcd.clear(); oldTime = millis(); using a generic pulse generator, a dedicated offers

By combining these resources with the techniques described in this article, you will have everything needed to successfully simulate and design YFS201‑based flow sensing systems using Proteus.

in standard Proteus libraries. The YFS201 is a physical sensor (commonly used with Arduino for water flow measurement), not a standard simulation model included with Proteus. void loop() // Every second, calculate flow if((millis()

void loop() // Every second, calculate flow if((millis() - oldTime) > 1000) detachInterrupt(digitalPinToInterrupt(2));

Because this approach gives you full control, you can also simulate temperature effects, voltage drift, or non‑linearities for more advanced studies.
