How It Works | কীভাবে কাজ করে
A load cell works by using strain gauges fixed inside or on the metal body. When weight is applied, the metal body bends slightly. This bending changes the electrical resistance of the strain gauges. The change is extremely small, so the signal must be amplified before a microcontroller can read it.
Load cell-এর ভিতরে strain gauge থাকে। যখন এর উপর weight বা force দেওয়া হয়, তখন metal body সামান্য bend করে এবং strain gauge-এর resistance পরিবর্তন হয়। এই signal খুব ছোট হওয়ায় সরাসরি Arduino বা ESP32 দিয়ে read করা যায় না। তাই HX711 amplifier module ব্যবহার করা হয়।
The HX711 module amplifies the small signal and converts it into digital data, which can then be processed by Arduino or ESP32 to display weight in grams or kilograms.
Why HX711 Is Required | কেন HX711 দরকার?
This load cell produces a very small millivolt-level signal. Arduino or ESP32 analog pins are not sensitive enough to read this signal accurately. The HX711 load cell amplifier is designed specifically for load cells and provides stable, high-resolution weight measurement.
এই sensor-এর output signal অনেক কম, তাই Arduino-এর analog pin দিয়ে সরাসরি accurate reading পাওয়া যায় না। HX711 module load cell signal amplify করে এবং digital output দেয়, ফলে accurate weight measurement করা যায়।

Basic Arduino + HX711 Example Code
Use this code only when the load cell is connected through an HX711 module.
#include "HX711.h"
#define DT 3
#define SCK 2
HX711 scale;
float calibration_factor = -7050; // Adjust after calibration
void setup() {
Serial.begin(9600);
scale.begin(DT, SCK);
scale.set_scale(calibration_factor);
scale.tare();
Serial.println("10kg Load Cell Ready");
}
void loop() {
float weight = scale.get_units(10);
Serial.print("Weight: ");
Serial.print(weight);
Serial.println(" kg");
delay(500);
}Calibration Note | ক্যালিব্রেশন নোট
For accurate measurement, calibration is required. After wiring the load cell with HX711:
- Upload the code
- Keep the platform empty
- Tare/zero the scale
- Place a known weight
- Adjust calibration factor until the displayed value matches the known weight
Accurate reading পাওয়ার জন্য calibration জরুরি। পরিচিত weight ব্যবহার করে calibration factor adjust করতে হবে।
