High Resolution Weight Logger Kit with Arduino Uno + LED
Build a High-Resolution Creep Detection Weight Logger with Arduino Uno
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Imagine setting up a load cell to continuously monitor a weight and automatically log every gram change to an SD card, complete with precise timestamps. This kit lets you build an instrument that can detect the slow, almost imperceptible creep deformation in materials — a critical measurement in mechanical and civil engineering experiments. With the Arduino Uno at its core, you'll assemble a system that records high-resolution weight data once per second, enabling long-term analysis of material behavior under static load.
What You'll Build
A standalone weight data logger that measures load using a 10kg load cell and HX711 amplifier, timestamped by a DS3231 real-time clock, and stored reliably on a microSD card. An OLED display shows live readings, and two tactile buttons let you control logging start/stop and file naming. You'll end up with a practical tool for studying viscoelastic creep, stress relaxation, or any slow-acting material deformation over hours or days.
What You'll Learn
- Precision analog signal conditioning with the HX711 24-bit ADC
- Implementing time-stamped data logging on SD cards using the Arduino SD library
- Configuring and reading a DS3231 RTC for accurate long-term timestamps
- Designing a user interface with an OLED display and push-button controls

Who This Kit Is For
This kit is ideal for B.Tech ECE, EEE, and Mechanical Engineering students working on data acquisition or material science projects. It’s a perfect fit for Smart India Hackathon teams needing a reliable weight logging solution, and for students at IITs, NITs, VIT, and BITS Pilani exploring real-time sensor logging. Makers in ATL Tinkering Labs (advanced level) will also find it a challenging yet rewarding build.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Our AI companion, trained specifically for this kit, will walk you through every connection and code block. You can also reach us via WhatsApp for a quick nudge in the right direction.
Can this kit be used for long-term logging, such as overnight experiments?
Absolutely. The DS3231 RTC keeps accurate time even without power, and the SD card can store months of data sampled once per second, making it perfect for overnight or multi-day creep tests.
What file format is the data saved in, and how can I open it?
Data is saved as a CSV file on the microSD card, with timestamp and weight columns. You can open it directly in Excel, Google Sheets, or any data analysis software for plotting creep curves.
Is the load cell suitable for measuring slowly increasing forces, like material creep?
Yes, the 10kg load cell and HX711 provide 24-bit resolution, capturing very small weight changes over long periods. The logging interval of 1 second is ideal for capturing the gradual deformation typical of creep in polymers or concrete samples.
HX711 + 10kg load cell logs weight every second to SD. Detects slow creep in materials under constant load.
