Zero-G Fluid Slosh Simulator Kit with ESP32 + MPU6050 — Master Propellant Slosh Dynamics for Space Applications

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

Simulating propellant slosh in a rotating tank is critical to understanding fluid behavior during rocket coast phases. This kit transforms an ESP32 into a high-speed data acquisition system that records pressure differentials across four MPX5010 sensors while dual MPU6050 IMUs track rotation rate and tank attitude — exactly the setup used in advanced aerospace labs to validate computational fluid dynamics models.

What You'll Build

You will assemble a fully instrumented rotating tank simulator. A DC gear motor spins a transparent vessel while four strategically placed pressure sensors detect minute differentials caused by slosh waves. The data is timestamped by a DS3231 RTC, logged to microSD, and displayed in real time on a 2.4-inch TFT. The result is a self-contained propellant dynamics testbed that can run autonomously for hours of experimentation.

What You'll Learn

• Sensor fusion with two MPU6050 IMUs to cancel common-mode vibrations and isolate true rotation-induced slosh
• Differential pressure measurement and signal conditioning using MPX5010 transducers and passive filtering networks
• Closed-loop PID motor control with the L298N driver for precise, repeatable rotation profiles
• Structured data logging to microSD with DS3231 timestamps, enabling correlation with external high-speed cameras or CFD outputs
