HX711 Proteus libraries let you simulate the HX711 ADC (commonly used with load cells) inside Proteus PCB/AVR simulations so you can test weighing circuits before hardware.

Standard versions of Proteus do not include the HX711 module by default. You must download external library files to add it to your component list. Where to Download

Look for repositories containing .LIB and .IDX files for the HX711 sensor.

Connect the DT and SCK pins to your microcontroller (like an Arduino Uno or PIC). Use the standard HX711.h library in your code to read the serial data.

Ensure you placed the files in the Data\LIBRARY folder, not just the root program folder.
