Library: Hx711 Proteus

The is a precision 24-bit ADC designed for load cells and weighing scales . It’s widely used with Arduino, STM32, and other microcontrollers.

Open Proteus and create a new schematic capture project. Use the Component Mode (click the button) to search for and add the following components to your workspace: Arduino Uno (or your preferred microcontroller library) HX711 Module / Chip (from your newly installed library)

: If you see "No Simulator Model," ensure you also copied any .MDF files that came with the library.

// These values are obtained by calibration // You will need to tweak these for your specific simulation scale.set_scale(2280.f); scale.tare(); // Reset the scale to 0 hx711 proteus library

Some advanced custom libraries bundle a dedicated "Load Cell" block alongside the HX711. If available, this block features interactive + and - buttons on-screen to instantly increment or decrement the weight value during active simulation. 4. Circuit Wiring Diagram Guide

: Connects to the HX711 via two digital pins (PD_SCK and DOUT). 💻 Step 4: The Arduino Code (Hex File)

| Problem | Solution | |---------|----------| | HX711 not found in Proteus | Check library folder + restart | | Simulation stuck at 0 | Add pull-up resistors on DOUT? Not needed in most models | | No response from HX711 | Swap A+/A- or E+/E- wires | | Library gives errors | Try a different HX711 model (TEP version is reliable) | The is a precision 24-bit ADC designed for

Since a load cell changes resistance based on weight, you can simulate this voltage variance using a standard variable resistor (potentiometer).

Thus, use simulation for , not for metrology-grade validation. Always test with real hardware before mass production.

In Proteus, add a to see weight readings.
