Locate a verified .IDX and .LIB file pair for the YF-S201 sensor from a trusted engineering forum or GitHub repository.

Pulse Generator / Digital Clock (from the Proteus Left Toolbar) Virtual Terminal (for serial debugging) Wiring Diagram Instructions

C:\Program Files (x86)\Labcenter Electronics\Proteus 8 Professional\LIBRARY

Load this optimized, interrupt-driven firmware into your Arduino IDE, compile it to generate a .hex file, and upload it to your Proteus microcontroller block.

| Wire Color | Pin Name | Connection | |------------|----------|-------------| | Red | VCC | 5V to 24V DC power supply | | Black | GND | Ground | | Yellow | SIGNAL | Output pulse (connect to digital input pin) |

if (currentMillis - previousMillis >= interval) detachInterrupt(digitalPinToInterrupt(flowSensorPin));

Which are you planning to use for your physical build?

To simulate the sensor, you need a specialized library file, often named WaterSensorTEP.LIB or similar. 1. Download the Library

Connect the to an interrupt-capable pin (e.g., Arduino Pin 2). 2. Setting Up the Simulation (Hex File)
