Once installed, you can build a complete weight measurement circuit:
In real life, you connect a load cell (e.g., 5kg, 20kg) to the HX711, and the HX711 connects to a microcontroller. The MCU reads digital weight values. hx711 proteus library
void loop() // In Proteus, the HX711 model usually outputs a specific raw value // which changes if you simulate a varying input on pins A+/A- Once installed, you can build a complete weight
Here is a simple test code:
