DIY Weight Measurement Using Load Cells & Arduino Microcontrollers

A Load Cell Sensor Arduino project is one of the most popular ways to learn about electronics, force measurement, and automation. By pairing a strain gauge load cell with an HX711 amplifier, makers can easily measure weight and force with an Arduino board. This setup is widely used in DIY weighing scales, robotics, IoT devices, and small industrial prototypes.

At Sensors and Gauges, we provide industrial-grade load cells for when your project needs to move from prototype to production.

Why Use a Load Cell with Arduino?

Arduino-based load cell setups are cost-effective, versatile, and educational.

Key Benefits:

• Affordable Entry Point – Great for students and hobbyists.

• Easy to Interface – Works with HX711 amplifier modules.

• Flexible Applications – From digital kitchen scales to IoT projects.

• Open-Source Ecosystem – Arduino libraries and tutorials available.

• Scalable – Start with SparkFun or generic load cells, then upgrade to ISO-calibrated models.

How to Connect a Load Cell Sensor to Arduino

A typical setup involves four components:

1. Load Cell Sensor (1kg–50kg capacity)

2. HX711 Load Cell Amplifier

3. Arduino Board (Uno, Nano, or Mega)

4. Display Module (optional, e.g., LCD or OLED)

Basic Wiring Guide:

• Red (Excitation+) → HX711 E+

• Black (Excitation–) → HX711 E–

• White (Signal–) → HX711 A–

• Green (Signal+) → HX711 A+

• HX711 DT & SCK pins → Arduino digital pins

Once connected, install the Arduino HX711 library, run calibration, and you can begin measuring weight.

Example Arduino Projects with Load Cells

• DIY Digital Kitchen Scale – Measure ingredients accurately.

• Smart Luggage Weigher – Avoid airline baggage fees.

• Robotic Force Feedback – Measure grip strength in robotic arms.

• IoT Weighing Systems – Send real-time weight data to the cloud.

• Agriculture Applications – Monitor animal feeding or silo levels.
