Load Cell Arduino – How to Build Accurate Weighing Systems with Arduino
DIY Projects Made Simple. Industrial Accuracy Made Accessible.
For hobbyists, students, and engineers, integrating a Load Cell with Arduino opens up a world of possibilities — from DIY electronic scales to robotics, automation, and IoT-enabled weighing systems. With just a load cell, an amplifier module, and an Arduino board, you can measure weight and force with impressive accuracy.
At Sensors and Gauges, we supply a wide range of load cells in Australia, ideal for Arduino projects, prototypes, and industrial test systems.
What is a Load Cell Arduino Setup?
A Load Cell Arduino setup uses a strain gauge load cell, connected through an amplifier (e.g., HX711), to an Arduino microcontroller. The Arduino reads the electrical signal from the load cell and converts it into a digital weight value.
Key components include:
Load Cell – The sensor that measures weight/force.
HX711 Amplifier Module – Boosts the millivolt signal from the load cell.
Arduino Board (Uno, Nano, Mega, etc.) – Processes the signal and outputs weight data.
Display / Serial Monitor – To view the readings in real-time.

How to Connect a Load Cell to Arduino
Wire the Load Cell to HX711 Amplifier
Red = Excitation+ (E+)
Black = Excitation– (E–)
White = Signal– (A–)
Green = Signal+ (A+)
Connect HX711 to Arduino
DT → Digital pin (e.g., D3)
SCK → Digital pin (e.g., D2)
VCC → 5V
GND → Ground
Upload HX711 Library and Arduino Code
Use Arduino IDE with the HX711 library to read weight data.
Calibrate the Load Cell
Place known weights on the load cell and adjust calibration factors in the code.
💡 Smart Tip: “Always calibrate your load cell Arduino system with standard weights to ensure accuracy — even small offsets can affect readings.”
