Zero-G Fluid Management Demo Kit – Replicate Propellant Slosh with ESP32 and Dual MPU6050 IMUs

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Control propellant motion in microgravity before a single gram of hydrazine leaves the ground. This kit lets you build a complete rotating test stand that monitors differential pressure across a sealed tank while dual MPU6050 IMUs correlate angular velocity and acceleration. You’ll wire four MPX5010 pressure transducers around a container, spin it with a DC gear motor, and log every data point with RTC timestamps to microSD – then watch live telemetry on a 2.4-inch TFT.

What You'll Build

A portable, self-contained fluid dynamics rig. Mount a sealed tank of your choice (water, silicone oil, etc.) on the motorized rotation axis, place four pressure sensors at symmetrical points, and acquire real-world slosh signatures. The ESP32 reads four analog pressure channels at up to 1 kHz, fuses that with dual MPU6050 gyro and accelerometer data, and streams both raw and processed values to the screen and SD card. You’ll reconstruct slosh frequencies, identify mode shapes, and validate simulations against experimental data – exactly the workflow used in ISRO’s propellant management tests.

What You'll Learn

• Configure multiple I2C MPU6050 sensors on a single bus using the AD0 address pin to prevent conflicts
• Calibrate four MPX5010 pressure sensors for differential measurements under constant centrifugal loading
• Implement sensor fusion between IMU angular velocity and pressure transients to characterize slosh mode damping
• Design a rugged data acquisition system with DS3231 RTC-timestamped logging to FAT32 microSD and real-time graphing on ILI9341 TFT

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

This kit is designed for aerospace engineering researchers and students at IITs, NITs, and BITS Pilani who need a low‑cost alternative to six‑figure slosh tables. It’s equally valuable for defence R&D teams prototyping liquid fuelling systems, Smart India Hackathon participants tackling propellant management problems, and space startup engineers building small‑satellite propulsion testbeds. If you’ve already mastered Arduino and want a project that matches graduate‑level experimental dynamics, you’re ready.
