Compact & Accurate Weighing Solutions for DIY and Professional Projects

A weight sensor 1kg is a compact load cell designed for precise measurement of small weights in applications such as kitchen scales, lab experiments, IoT devices, and portable weighing systems. With high sensitivity and accuracy, it’s the perfect solution for makers, researchers, and product developers who need precise force or weight detection at a low capacity.

At Sensors and Gauges, we supply high-quality 1kg weight sensors and HX711 amplifier kits that integrate seamlessly with Arduino, Raspberry Pi, and ESP32 platforms.

Components You Need

To build a 1kg weighing system, you typically need:

• 1kg Load Cell / Weight Sensor

• HX711 Amplifier Module (boosts mV signals)

• Microcontroller (Arduino, Raspberry Pi, ESP32)

• Breadboard & Wires for prototyping

• Calibration Weights to set accuracy

How to Connect a 1kg Weight Sensor

1. Wire Load Cell → HX711 Module

   • Red → E+

   • Black → E-

   • White → A-

   • Green → A+

2. HX711 → Arduino/ESP32

   • DT → GPIO pin

   • SCK → GPIO pin

   • VCC → 5V

   • GND → GND

3. Install Libraries – e.g., HX711 Arduino or Python libraries

4. Calibrate using a known weight (e.g., 500g)

5. Start Measuring Real-Time Weight
