What is a 20kg Load Sensor?

A 20kg load sensor is a strain gauge-based transducer that converts applied weight or force into an electrical signal. These sensors are typically used in:

  • Weighing Scales (kitchen, bench-top, or packaging)

  • IoT Projects (smart inventory systems, connected food scales)

  • Industrial Applications (filling machines, material testing)

Circuit Setup – Load Sensor 20kg with HX711

To use a 20kg load sensor with Arduino or Raspberry Pi, you’ll need:

  • 20kg Load Cell

  • HX711 Amplifier Module

  • Microcontroller (Arduino/ESP32/Raspberry Pi)

  • Wiring

Connection Diagram:

  • E+ → Red (Excitation +)

  • E- → Black (Excitation -)

  • A+ → White (Signal +)

  • A- → Green (Signal -)

  • HX711 → Arduino (DT → D2, SCK → D3)

Sample Arduino Code:


#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 scale.tare(); } void loop() { Serial.print("Weight: "); Serial.print(scale.get_units(), 2); Serial.println(" kg"); delay(500); }
