Structural Load Monitor for Airframe Kit with Arduino Mega + LED
Structural Load Monitor for Rocket Airframe Kit with Arduino Mega & OLED
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
In rocketry, knowing the bending loads your airframe experiences during static ground tests is crucial for structural integrity. This kit lets you instrument three points on your rocket body with 50 kg load cells, record time-stamped data, and display live readings — all powered by an Arduino Mega.
What You'll Build
You’ll assemble a triple-channel strain gauge data acquisition system that attaches to a rocket airframe. Once built, you can run static load tests and see real-time force curves on the OLED. All measurements are logged to a microSD card with precise RTC timestamps, ready for analysis in MATLAB or Python. This is a field-ready instrument for any serious student rocketry team.
What You'll Learn
- Wiring and calibrating HX711 load cell amplifiers for 3-channel simultaneous measurement
- Programming Arduino Mega to read multiple sensors, drive an OLED display, and log data to microSD
- Interfacing a DS3231 real-time clock to timestamp each data sample
- Applying noise filtering and decoupling capacitors for stable analog signals during testing

Who This Kit Is For
Built for advanced electronics and aerospace engineering students, this kit is ideal for B.Tech ECE, EEE, and Mechanical students working on rocket design projects. It’s a perfect fit for rocketry clubs at IITs, NITs, VIT, BITS Pilani, and other engineering colleges participating in competitions like Smart India Hackathon or CANSAT. CBSE Class 11-12 students with strong Arduino background can also take it on with guidance. If you need a reliable, pre-assembled sensor suite for your static test stand, this is the kit.
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 walks you through every connection with photos and code snippets. If you need a human touch, WhatsApp message us — reply typically within 2 hours during business hours.
Can I increase the load range beyond 50 kg?
You can swap in higher-capacity load cells (up to 100 kg) as long as they share the same Wheatstone bridge configuration; the HX711 amp and code will work. Check our support for recommendations.
Do I need a separate power supply for the Arduino Mega?
A standard 9V battery powers the system for about 4 hours of logging. For continuous bench testing, you can use a 12V DC adapter instead.
Can I log data to a PC directly instead of microSD?
Yes, you can stream data over USB serial to any serial monitor or Python script. The microSD acts as a standalone logger, but you can skip it if you prefer live PC logging.
Strain gauge and HX711 measure structural bending loads at three points along rocket airframe during static test.
