What is a 1kg Load Sensor?

A 1kg load sensor works on the principle of a strain gauge. When weight is applied, the load cell deforms slightly, changing its resistance. This tiny signal is then amplified by an HX711 or ADC module to produce accurate digital readings.

Typical specifications of a 1kg load sensor include:

  • Capacity: 0–1kg (1000g)

  • Accuracy: ±0.01% of full scale

  • Output: ~1mV/V

  • Excitation Voltage: 5V DC

  • Form Factor: Compact single-point aluminum body

Circuit Setup – Load Sensor 1kg with Arduino

To integrate a 1kg load sensor with an Arduino or Raspberry Pi, you need:

  • 1kg Load Cell

  • HX711 Amplifier Module

  • Arduino/ESP32/Raspberry Pi

  • Wires + Breadboard

Wiring Diagram (Load Cell → HX711 → Arduino):

  • E+ → Red

  • E- → Black

  • A+ → White

  • A- → Green

  • DT → Arduino D2

  • SCK → Arduino D3

Arduino Code Example:


#include "HX711.h" HX711 scale; #define DT 2 #define SCK 3 void setup() { Serial.begin(9600); scale.begin(DT, SCK); scale.set_scale(420.f); // Calibration factor for 1kg scale.tare(); // Reset scale to zero } void loop() { Serial.print("Weight: "); Serial.print(scale.get_units(), 3); // three decimal places for accuracy Serial.println(" g"); delay(500); }
