Standard versions of Proteus (up to the latest releases) typically do not include the HX711 schematic symbol or the simulation model in the default LIBRARY folder. Consequently, when a user attempts to design a circuit involving weight measurement, they encounter a "Library Not Found" error or are forced to simulate the ADC functionality abstractly, which defeats the purpose of hardware-in-the-loop testing. Therefore, the acquisition of a specific HX711 library package is a prerequisite for realistic simulation.
In the Arduino IDE, go to -> Include Library -> Manage Libraries . Search for "HX711 Arduino Library by Bogdan Necula" and click install. 2. Sample Code
| HX711 Pin | Connect To | |-----------|-------------| | VCC | +5V (Arduino) | | GND | GND (Arduino) | | DT (Data) | Arduino Pin A1 (or any digital pin) | | SCK (Clock) | Arduino Pin A0 | | E+ | Load Cell excitation + | | E- | Load Cell excitation - | | A+ | Load Cell signal + | | A- | Load Cell signal - | hx711 proteus library download
#include "HX711.h"
Download the compressed file (usually a .zip or .rar folder). Extract the contents using software like WinRAR or 7-Zip. HX711.LIB (Library File) HX711.IDX (Index File) Sometimes a .HEX file for active simulation behaviors. 2. Installing the HX711 Library in Proteus Standard versions of Proteus (up to the latest
Typically, the path is: C:\Program Files (x86)\Labcenter Electronics\Proteus 8 Professional\DATA\LIBRARY
The is the industry standard for interfacing load cells with microcontrollers like Arduino. However, testing a physical weight-scale circuit can be difficult without an exact physical weight. The HX711 Proteus library provides the ideal solution by allowing you to simulate the entire system virtually before building any hardware. In the Arduino IDE, go to -> Include
Search for . Select it and place it onto your workspace. Pick a microcontroller (e.g., Arduino Uno / ATmega328P ).
