Hx711 Proteus Library New! Link

for the HX711, allowing engineers to simulate load cell interfaces before hardware fabrication. Seeed Studio 2. System Architecture The simulated system consists of three primary stages: Sensor Input (Wheatstone Bridge):

If using Channel B, connect secondary sensor inputs to and B- . Digital Output Side (HX711 to Microcontroller):

#include "HX711.h" // Define Pins const int LOADCELL_DOUT_PIN = 3; const int LOADCELL_SCK_PIN = 2; HX711 scale; void setup() Serial.begin(9600); scale.begin(LOADCELL_DOUT_PIN, LOADCELL_SCK_PIN); // Set scale factor for simulation scale.set_scale(2280.f); scale.tare(); void loop() if (scale.is_ready()) long reading = scale.get_units(10); Serial.print("Weight: "); Serial.println(reading); else Serial.println("HX711 not found."); delay(1000); Use code with caution. Running the Simulation Compile the code in Arduino IDE and export the file. hx711 proteus library

The HX711 itself is just an ADC. The quality of your simulation depends heavily on how you model the load cell. Instead of using a simple potentiometer, consider creating a that maps voltage to weight. For instance, define a 5 kg load cell that outputs 0‑10 mV at full scale—then scale that to a voltage that the HX711 expects. You can do this by placing an ideal voltage source whose output you control manually or through a script. for the HX711, allowing engineers to simulate load

Proteus includes a tool that allows you to design a new component from scratch. The process involves:

To interact with the HX711 model, use the standard HX711 library within the Arduino IDE. Arduino Sketch
