Greenhouse Rocket Dual Deployment Altimeter Kit - Arduino Nano BMP280
Greenhouse Rocket Dual Deployment Altimeter - Arduino Nano, BMP280 & MPU6050 Apogee Control with Data Logging
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 Greenhouse project is a full-featured rocket altimeter system engineered for reliable dual deployment. Using a sensitive BMP280 barometric pressure sensor and an MPU6050 inertial measurement unit, the system detects launch, tracks altitude during coast, and triggers parachute deployment at apogee and a secondary event at 300 meters. All flight data is timestamped and logged to a MicroSD card through the DS3231 real-time clock, giving you a complete telemetry record for post-flight analysis. This kit puts the capability of a commercial flight computer into your hands.
What You'll Build
You will assemble, calibrate, and fly a rocket-borne dual deployment altimeter that autonomously controls two parachute ejection charges. The board integrates barometric pressure sensing for altitude determination, accelerometer data for launch detection, dual 5V relays to fire igniters, and a logging subsystem that records altitude, vertical velocity, and event timestamps. At the end you have a compact, battery-powered module ready for a 38mm or larger rocket airframe.
What You'll Learn
- Barometric altitude sensing and filtering with BMP280 for reliable apogee detection
- Sensor fusion using accelerometer and pressure data to pinpoint launch and motor burnout
- Dual-deployment logic: staging relay triggers at apogee and a configurable lower altitude
- Flight data logging to MicroSD with precise timestamps from the DS3231 RTC

Who This Kit Is For
Advanced model rocket enthusiasts building high-power dual deployment systems, B.Tech aerospace or ECE students tackling CanSat or Smart India Hackathon flights, and rocketry clubs at IIT, NIT, VIT, or BITS seeking a proven flight computer reference design. If you have soldering experience and understand basic Arduino programming, this kit takes you from components to a calibrated flight-ready payload.
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, describe the issue, and you'll get guidance right at your bench. WhatsApp and email support are standing by if you need human help.
How does the dual deployment logic work?
The code uses BMP280 pressure readings to detect apogee via a zero-velocity criterion and MPU6050 data to lock out ground-level events. At apogee, Relay 1 fires; at 300m, Relay 2 fires to deploy the main parachute.
Can I fly this without a rocket? I want to test first.
Absolutely. The MPU6050 accelerometer and pressure sensor let you simulate launch and apogee on the bench by tilting and changing elevation; the AI companion includes a test script for ground validation.
Is soldering required, and is everything included?
Yes, thorough soldering on the prototype board is needed for a reliable flight build. The kit includes a soldering iron and solder wire specifically for this assembly.
Greenhouse - BMP280 + MPU6050 detect launch, apogee and fires dual deployment relays at apogee and 300m with SD data log.
