Rocket Propellant Mass Flow Simulator Kit with Arduino Uno + Sensor
Rocket Propellant Mass Flow Simulator Kit — Solve the Tsiolkovsky Equation 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.
This kit transforms an Arduino Uno into a rocket propellant mass flow simulator. You'll measure the diminishing mass of a water rocket in real time, compute instantaneous flow rate, and solve Tsiolkovsky's rocket equation to predict thrust. Perfect for aerospace engineering students validating theory with hardware.
What You'll Build
A complete data-acquisition system that logs mass, flow rate, and time onto a microSD card. The 0.96-inch OLED displays live readings, and you'll have a working model to demonstrate the rocket equation in lab reports or competitions.
What You'll Learn
- Calibrate an HX711 load cell to measure mass loss in a water rocket
- Interface a YF-S201 flow sensor to compute instantaneous flow rate
- Program an Arduino to solve Tsiolkovsky's equation in real time
- Log timestamped data to a microSD card using DS3231 RTC for accurate time-stamping

Who This Kit Is For
Built for B.Tech students in aerospace, ECE, and mechanical engineering, as well as participants in Smart India Hackathon and rocketry competitions. This kit is also used in advanced ATL Tinkering Labs and by hobbyists at makerspaces across India.
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 guides you step-by-step, and you can reach our support team via WhatsApp for real-time assistance.
Can I use this kit with a solid propellant rocket motor instead of water?
The load cell and flow sensor are optimized for water-based mass flow measurement, but you can adapt the setup for small solid motors with caution.
Does the kit include software code?
Yes, the AI companion provides full Arduino code for calibration, data logging, and solving the Tsiolkovsky equation.
Can I export data for analysis in MATLAB or Python?
Absolutely — the microSD logs CSV files with timestamps, which you can directly import into MATLAB, Python, or Excel.
HX711 load cell measures diminishing mass of water rocket. Flow rate computed and Tsiolkovsky equation solved.
