Greenhouse Multi-Stage Rocket Sequencer Kit - Arduino Mega BMP280
Greenhouse Multi-Stage Rocket Sequencer Kit: Program Altitude-Triggered Stage Separation with Arduino Mega & Dual 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.
Transform your high-power rocket into a multi-stage vehicle with reliable, altitude-based stage separation. This kit lets you build a flight-optimized sequencer that reads altitude from dual BMP280 barometers, verifies orientation with an MPU6050 IMU, and fires relays at preset altitudes. Built-in abort logic shuts down the sequence if any sensor detects an anomaly, protecting your payload and airframe. Perfect for rocketry teams, CanSat competitors, and advanced hobbyists pushing the limits of amateur space simulation.
What You'll Build
You'll assemble and program a complete avionics module that rides inside your rocket. The system logs altitude, acceleration, and event timestamps to microSD, displays real-time telemetry on the OLED, and controls up to 8 external relays for stage separation, parachute deployment, or other sequenced actions. Dual BMP280 sensors provide redundant pressure data, and the MPU6050 detects tumbling or excessive spin to trigger an abort.
What You'll Learn
- Fusing altitude data from two barometric sensors for high-confidence stage triggers
- Programming a state machine on Arduino Mega to handle ascent, separation, and abort events
- Driving high-current relays with diode suppression and timing logic
- Logging flight data to microSD with DS3231 RTC timestamps for post-flight analysis

Who This Kit Is For
Advanced rocketry enthusiasts, B.Tech aerospace and ECE students prototyping avionics for CanSat or CubeSat competitions, participants in Smart India Hackathon hardware tracks, and anyone building a multi-stage rocket sequencer with abort logic. If you've already launched single-stage high-power rockets and want to progress, this kit gives you a flight-tested reference design you can customise.
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?
Open the AI companion from the QR code or message us on WhatsApp; the assistant is specific to the Greenhouse sequencer wiring and code, and our team can step in if needed.
Can this sequencer handle more than two stages?
Yes, the 8-channel relay module lets you assign as many separation events as your rocket design needs, up to four independent two-relay triggers or custom sequences.
How does the abort logic decide to fire?
The firmware monitors acceleration magnitude, angular velocity, and vertical speed derivative from the MPU6050 and BMP280 pair. If values exceed safe thresholds, all relays are disarmed within 100ms.
Do I need to provide my own rocket airframe and motors?
Yes, this kit supplies only the avionics; you must supply the rocket vehicle, motors, and igniters. All electronics are sized to fit standard 4-inch and larger high-power rocket avionics bays.
