Arduino Mega 4-Port Hydrostatic Pressure Test Rig — Safety-Interlocked Rocket Casing Validation

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 turns raw components into a bench-top hydrostatic test station that validates the structural integrity of rocket motor casings before live firing. Four MPX5700 pressure transducers monitor casing ports simultaneously while an Arduino Mega runs a hardwired safety interlock—cutting off the pump the instant any pressure channel exceeds its threshold. The result is a repeatable, data-logged, safety-first protocol used by university rocket teams and serious hobbyists.

What You'll Build

A DIN-rail enclosed pressure data acquisition system. You will connect four analog sensors to the Mega’s ADC, calibrate them for 0–700 kPa, and write a firmware sketch that reads all channels, logs time-stamped data to a microSD card, and renders live pressure curves on a 2.4-inch TFT display. A 4-channel relay module, driven by redundant safety logic with diodes, acts as a hard cut-off for the external pump, ensuring that a single sensor fault can still trigger an immediate shutdown.

What You'll Learn

• Configuring MPX5700 analog pressure transducers for precise hydrostatic range and linearity
• Implementing a multi-channel redundant safety interlock using relays, diodes, and polling loops
• Timing sensor reads with a DS3231 RTC and storing structured logs on a microSD using SPI
• Soldering noise-resistant analog front-ends on prototyping boards and housing them in a DIN rail enclosure

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

Aerospace and mechanical B.Tech students building Smart India Hackathon pressure-testing modules, propulsion teams at IITs, NITs, or BITS Pilani qualifying student-built casings, and experienced amateur rocketeers who need a repeatable hydrostatic protocol rather than ad-hoc plumbing. Prior Arduino coding and basic soldering are assumed.

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.
