Yf-s201 Proteus Library Jun 2026

Good for testing code logic and timer interrupts. Do not rely on it for precise flow behavior – use the real sensor for hardware validation.

: Every time the magnet passes the Hall Effect sensor, it triggers a pulse. yf-s201 proteus library

Proteus simulates interrupts, but the signal from the YF-S201 might be too fast or have slow rise times. Fix: Add a 10k pull-up resistor on the signal line. Also, in the YF-S201 properties, reduce the maximum frequency (set a lower flow rate like 1 L/min for testing). Good for testing code logic and timer interrupts

void setup() pinMode(flowPin, INPUT); attachInterrupt(digitalPinToInterrupt(flowPin), pulseCounter, RISING); Serial.begin(9600); in the YF-S201 properties
