Connect the DOUT (Data Output) pin of the HX711 to digital pin D3 on the Arduino. Connect the PD_SCK (Power Down and Serial Clock) pin to digital pin D2 . Power Supply: Connect the VCC / VDD pins to a
Ensure your potentiometer is wired correctly to generate a true differential voltage across A+ and A- . If the voltages on both pins remain completely identical, the ADC output will register as static or zero noise.

Complete Guide to Integrating the HX711 Proteus Library for Weight Scale Simulations
Since Proteus does not include the HX711 module by default, you must download a third-party module library. Step 1: Download the Library Files hx711 proteus library
To simulate this component, you need the specific Proteus model files ( .LIB and .IDX files) and, if available, the hex file for the simulation model.
The HX711 is a popular 24-bit analog-to-digital converter (ADC) used for weighing scales and other high-precision applications. Proteus, a widely-used electronics simulation software, provides a library for simulating the HX711. In this article, we'll explore the HX711 Proteus library, its features, and how to use it effectively in your simulations.
The is a specialized simulation component used to model the HX711 24-bit Analog-to-Digital Converter (ADC) , primarily designed for weigh scales and industrial control applications . Since Proteus does not include this sensor in its default installation, you must manually download and integrate third-party library files (typically .LIB and .IDX ) to simulate load cell interfacing.

Search for a (a high-precision variable potentiometer) to act as your dummy load cell sensor.
What (Arduino, PIC, STM32) are you targeting?
consisting of Clock (PD_SCK) and Data (DOUT) lines.
Once the HX711 Proteus library is installed and the load cell simulation is set up, you can program your microcontroller to read the weight. The following is an example of an Arduino code snippet that interfaces with the HX711 module: If the voltages on both pins remain completely
(Note: Replace this with your actual download link)
To create a working simulation, you will need the HX711 model, an Arduino (e.g., Arduino Uno or Nano), and a variable resistor (potentiometer) to simulate the analog load cell changes. Component List HX711 Model Potentiometer (Pot-HG) - Represents the load cell input Virtual Terminal - To view output data Wiring Steps Connect HX711 DOUT to Arduino Pin D3 . Connect HX711 SCK to Arduino Pin D2 . Connect VCC to 5V and GND to Ground.
To make the HX711 component appear in your Proteus object selector, copy the downloaded files into your Proteus installation directory. For Proteus 8 or Newer: Close Proteus completely.
Many beginners ignore the "Channel A" and "Channel B" pin properties in the simulation environment, assuming they are purely physical. In Proteus simulation, the virtual behavior of the HX711 is modeled. Therefore, one common fix is to double-click the HX711 component in your schematic, navigate to the properties, and set the "Channel A" and "Channel B" pins to and "PD_SCK" and "DOUT" to OUTPUT . Failure to do so can result in invalid simulation logic levels.
Because Proteus does not include the HX711 in its native component library, adding a custom third-party HX711 library is mandatory to simulate weight-sensing applications. How to Download and Install the HX711 Proteus Library
