. Since Proteus does not include a native HX711 component, a dedicated third-party library is required to bridge the gap between a virtual load cell and a microcontroller like Arduino. Core Components of the Simulation
By the end, you will be able to simulate a complete digital weighing system entirely inside Proteus.
HX711 scale;
circuit made of four resistors or a specialized sensor model that provides variable voltage. Microcontroller Board : Usually an Arduino Uno or Nano
The HX711 itself is just an ADC. The quality of your simulation depends heavily on how you model the load cell. Instead of using a simple potentiometer, consider creating a that maps voltage to weight. For instance, define a 5 kg load cell that outputs 0‑10 mV at full scale—then scale that to a voltage that the HX711 expects. You can do this by placing an ideal voltage source whose output you control manually or through a script. hx711 proteus library
Click the button at the bottom left of Proteus to start the execution. As you toggle the percentage values up and down on your POT-HG potentiometer, you should see the calculated weight values change dynamically on the virtual LCD screen. Common Troubleshooting Steps
Obtain the library files (usually a .ZIP containing HX711.LIB and HX711.IDX ). HX711 scale; circuit made of four resistors or
Proteus includes a tool that allows you to design a new component from scratch. The process involves:
If Proteus crashes or errors out when hitting play, make sure you placed both the .IDX and .LIB files inside the correct root LIBRARY folder and restarted Proteus before running. Instead of using a simple potentiometer, consider creating
Simulating load cell projects requires a dedicated software component to emulate the HX711 analog-to-digital converter (ADC). Proteus Design Suite does not include a native HX711 model in its default component library.
In Proteus, add a to see weight readings.
