When designing electronic projects involving weight measurement, the HX711 is the go-to load cell amplifier. It is cheap, precise, and easy to interface with microcontrollers like Arduino, PIC, or AVR. However, simulating a weight scale project in Proteus can be frustrating because the default Proteus software does not include an HX711 model.
What is HX711?
If you cannot find a ready-made library, you can simulate the HX711 by using an Arduino Uno in Proteus with pre-written code. This is not a native library but works for testing. hx711 proteus library download
