Drone Altimeter Kit with Arduino Mega + BMP280
Programmable Multi-Stage Separation Sequencer with Arduino Mega, Dual BMP280 Altimeters, and Abort Logic
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
When you’re simulating high-stakes stage separation on a model rocket or a high-altitude drone, guessing altitudes is not an option. This kit turns an Arduino Mega into a hardened multi-stage relay sequencer — firing stage separation charges at two independent BMP280‑verified altitude thresholds, with an MPU6050‑enabled abort routine that halts the sequence if attitude exceeds a configurable safety cone. Everything you need to prototype a mission‑critical staging controller lands in one box.
What You'll Build
You will assemble and program a dual‑redundant altimeter system. Two BMP280 sensors cross‑check altitude readings; if they diverge beyond a tolerance, the onboard abort logic locks out the 8‑channel relay module. On a successful ascent, the relays fire sequentially at your programmed altitude steps — for example, igniting a second‑stage motor at 300 metres after a verified straight flight. An OLED displays real‑time status, while every pressure, acceleration, and event timestamp logs to microSD for post‑flight analysis.
What You'll Learn
- Implementing sensor fusion with MPU6050 gyro/accel data for real‑time attitude monitoring
- Designing a fault‑tolerant state machine that triggers abort on sensor mismatch or excessive tilt
- Calibrating and cross‑validating two BMP280 barometric sensors for altimetry redundancy
- Logging time‑stamped telemetry (RTC) to microSD and driving a live OLED HUD

Who This Kit Is For
This kit is built for advanced makers and engineering students who need a reliable, self‑contained stage controller for rocketry and drone experiments. It fits right into B.Tech ECE/EEE capstone projects at IITs, NITs, and VIT, Smart India Hackathon challenges requiring autonomous flight sequencing, or ATL Tinkering Lab mentors prototyping launch vehicles. If you have prior Arduino experience and want to move from single‑sensor dataloggers to real‑time redundant control architectures, this is your next step.
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?
Scan the QR code on the box to start a session with our AI companion. It knows every connection, calibration step, and the sample abort logic code. You can also drop a WhatsApp message with a photo of your wiring, and we’ll help you debug within hours.
Can I use this kit for a water rocket or a low‑power model?
Absolutely. The relays can trigger any low‑current ignition, servo release, or parachute deployment as long as the actuator fits within the 8‑channel capacity. The abort logic is configurable; you can relax or tighten the attitude cone to match your airframe.
Does the kit include wireless telemetry?
This kit focuses on onboard logging and local display. If you need real‑time RF downlink, you can add an HC‑12 or LoRa module to the Arduino’s spare serial port — the code structure we provide has a dedicated telemetry function ready to adopt it.
What abort conditions does the pre‑loaded logic check?
The sample code monitors dual‑BMP280 altitude agreement (max 2‑metre divergence) and MPU6050 tilt (configurable from 10° to 30°). If either condition fails, all relay outputs are locked off, and the OLED shows the abort reason. You can extend the state machine with your own custom rules.
