⚠️ Proteus does not include an HX711 model by default. You must download or create a library.
Verify that your .LIB and .IDX files are placed inside the core installation Data\LIBRARY path, rather than user documents paths. Always restart Proteus after moving files.

The HX711 is a precision 24-bit ADC designed for high-precision electronic scales. It integrates a low-noise programmable amplifier (PGA) with gains of 32, 64, and 128. Because load cells output very small voltage changes (in millivolts), a standard Arduino ADC isn't sensitive enough. The HX711 amplifies this signal and converts it to a digital value readable by a microcontroller.
