Build a Reliable Apogee Parachute Ejection System with Arduino Nano + BMP280

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

The moment your model rocket arcs over and begins to fall, the BMP280 senses the subtle pressure rise after apogee. Within milliseconds, your Arduino Nano commands a relay to dump capacitor energy through a bright LED — simulating the pyro charge that pops a parachute. It’s the brain of any serious model rocket recovery, and you’ll build it, code it, and watch it work on the bench before it ever leaves the launch pad.

What You'll Build

You’ll wire a compact flight computer on a breadboard that reads barometric altitude, identifies the highest point of flight, and triggers a high-current relay exactly at apogee. Three red LEDs connected to a capacitor bank flash in sequence, mimicking a real ejection charge. The system runs on a 9V battery and can be integrated into any model rocket airframe—perfect for school rocketry clubs or personal space simulators.

What You'll Learn

• Read and interpret BMP280 pressure data in real time with an Arduino Nano
• Implement a robust apogee detection algorithm based on pressure inflection
• Control a 5V relay safely using transistor logic and flyback diodes
• Design a capacitor discharge circuit to visualize pyro firing sequences

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

CBSE Class 11–12 students building physics investigatory projects, B.Tech ECE/EEE rocketry club members, and participants in Smart India Hackathon or ATL Tinkering Lab challenges will find this kit a leap from theory to a functional recovery system. IIT, NIT, VIT, and BITS teams prototyping model rocket avionics can validate apogee logic and ejection timing in hours, not weeks.

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.
