Load Cell Code for ESP32 | Complete Guide with HX711 Example

Measure Weight with ESP32 + HX711 + Load Cell

A Load Cell Code for ESP32 enables makers and engineers to integrate precise weight measurement into IoT projects, DIY smart scales, and industrial prototypes. By combining an ESP32, an HX711 amplifier, and a load cell, you can capture accurate weight data and send it to displays, IoT dashboards, or cloud platforms.

At Sensors and Gauges, we provide ESP32-compatible load cells, HX711 modules, and weighing kits to help you prototype and deploy smart weighing solutions with ease.

Installing HX711 Library

In Arduino IDE:

Go to Sketch > Include Library > Manage Libraries
Search for “HX711”
Install the library by Bogdan Necula / Olkal

Sample Code: ESP32 + Load Cell

#include "HX711.h"

// Pin assignment (adjust to your wiring)
#define DT 18
#define SCK 19

HX711 scale;

void setup() {
  Serial.begin(115200);
  scale.begin(DT, SCK);

  Serial.println("Initializing Load Cell...");
  
  // Calibration step – adjust with your calibration factor
  scale.set_scale(2280.f);  // Example factor
  scale.tare();             // Reset scale to 0

  Serial.println("Place a known weight to calibrate...");
}

void loop() {
  if (scale.is_ready()) {
    long reading = scale.get_units(10); // Average of 10 readings
    Serial.print("Weight: ");
    Serial.print(reading);
    Serial.println(" g"); // Or kg depending on calibration
  } else {
    Serial.println("HX711 not found.");
  }
  delay(1000);
}

Calibration Process

Upload the code and open Serial Monitor.
Place a known weight (e.g., 500g).
Adjust scale.set_scale(2280.f) until the reading matches the actual weight.
Save the factor for permanent use.
