Capture Real‑Time Thrust Curves with the Thrust Stand Force Gauge Kit — Arduino Uno, HX711 Load Cell & 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.

A single test fire of a model rocket motor hides a wealth of performance data — peak thrust, burn time, total impulse — if only you can capture it cleanly. This kit turns that challenge into a repeatable experiment. Mount a small motor or propeller on the load cell, run a burn, and watch the OLED paint the thrust curve in real time while the microSD stores a timestamped record for later analysis. It is rocketry simulation made tangible, without guesswork.

What You'll Build

You will assemble a bench-top thrust stand that quantifies the axial force produced by a hobby rocket motor, EDF, or even a brushless propeller setup. The HX711 load cell delivers millivolt-level precision, the Arduino converts it to grams-force, and the OLED graphs the live signal. Every test run is saved with a DS3231 RTC stamp to microSD, so you can overlay multiple thrust curves and calculate impulse exactly as ISRO or NASA teams would at model scale.

What You'll Learn

• Calibrate a 5 kg load cell using the HX711 24-bit ADC and a known reference weight
• Display real-time force readings and a scrolling thrust curve on a 0.96-inch OLED
• Timestamp sensor data with the DS3231 RTC and log it to microSD as structured CSV
• Analyse thrust impulse — the area under the force-time curve — by post-processing logged data

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

CBSE Class 11–12 students will find it a direct fit for physics investigatory projects on force measurement and impulse. B.Tech aerospace or mechanical engineering undergrads can use it to validate solid motor thrust curves before static firing, a common requirement at IIT and NIT rocketry clubs. ATL Tinkering Lab mentors and Smart India Hackathon teams working on drone or propulsion prototypes get an accurate, reusable force gauge that logs data autonomously — no laptop required during the test stand run.
