Before starting the simulation, it is essential to understand how the hardware operates so you can model it accurately.
If a dedicated library is unavailable, you can simulate the sensor's behavior using standard Proteus components: Clock Generator Pulse Generator

void loop() // Every second, calculate flow if((millis() - oldTime) > 1000) detachInterrupt(digitalPinToInterrupt(2));
Or use I2C LCD (PCF8574) to save pins.
This defines the physical layout for PCB design in ARES—the pad locations, dimensions, and hole patterns that determine manufacturability. Though not required for pure simulation, it's essential for physical production.
for new Proteus users. Always verify that any library you download is compatible with your specific Proteus version before installation. Before starting the simulation, it is essential to
By following this guide, you can simulate complete water flow monitoring systems, debug interrupt-driven code, and visualize flow rates on virtual LCDs—all before ordering a single component.
