Hx711 Proteus Library Download <DELUXE ⟶>

// Pseudo: clock SCK and read DOUT
pinMode(SCK_PIN, OUTPUT);
pinMode(DOUT_PIN, INPUT);
while(digitalRead(DOUT_PIN)); // wait for data ready
for(int i=0;i<24;i++) 
digitalWrite(SCK_PIN, HIGH);
delayMicroseconds(1);
// read bit
digitalWrite(SCK_PIN, LOW);

If you see a 24-bit value changing on the virtual terminal, your library is working.

If you are working on a weight measurement or load cell project in Proteus, the HX711 is a must-have component. This 24-bit ADC is specifically designed for load cells and pressure sensors, making it ideal for digital scales, industrial automation, and IoT-based weighing systems.

However, Proteus does not include the HX711 in its default library. In this guide, I’ll show you where to download a working HX711 library, how to install it, and how to simulate it successfully. hx711 proteus library download

#include "HX711.h"
HX711 scale;
void setup() 
Serial.begin(9600);
scale.begin(A1, A0); // DT, SCK
scale.set_scale(2280.f); // Calibration factor
scale.tare(); // Reset to zero

void loop() 
float weight = scale.get_units(5); // Average of 5 readings
Serial.print("Weight: ");
Serial.print(weight);
Serial.println(" grams");
delay(500);

Upload the compiled .hex file to the Arduino model in Proteus and watch the virtual serial output.

Since Labcenter Electronics (the creators of Proteus) does not manufacture this part, you must download a user-created model. There are two common versions available on engineering blogs and forums:

Steps to Download:

If you cannot get the HX711 library to work, consider these alternatives: // Pseudo: clock SCK and read DOUT pinMode(SCK_PIN,

| Alternative | Pros | Cons | |-------------|------|------| | Generic ADC (e.g., MCP3201) | Built into Proteus | Only 12-bit resolution | | Simulate using I2C EEPROM + Op-Amps | No download needed | Complex setup | | Use a different simulator (LTspice) | Accurate analog response | No microcontroller co-sim | | Replace with load cell amplifier (INA125) | Native Proteus model | Requires more components | | Use a pre-built Proteus project file | Plug-and-play | Hides learning details |

The most reliable sources are user forums where engineers share and update models.

The HX711 is a popular 24-bit ADC for load cells/strain gauges. In Proteus (a circuit simulation and PCB design tool) you can simulate designs that include the HX711 if you have a suitable Proteus library (component model or symbol + simulation model). A useful write-up should explain where to get a library, how to install it, how to wire and simulate the module, and alternatives if no ready-made model exists.
