Altitude Hold Balloon Controller Variant 25 Kit with Arduino Uno + BMP280
Achieve Stable Altitude Hold with the Arduino Uno + BMP280 Balloon Controller Kit
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Master the physics of buoyancy and closed-loop control by building a helium-filled balloon that hovers at a precise altitude. Using BMP280 pressure readings, an Arduino Uno commands two SG90 servos to open or close a helium release valve, maintaining steady flight for experimental data collection or the challenge of autonomous levitation.
What You'll Build
Assemble a self-regulating high-altitude platform that senses altitude, vents helium, and stabilizes at your target pressure level. You'll fabricate a servo-actuated valve mechanism on a prototype board and program the control loop to respond to BMP280 readings, while logging flight data with precision timestamps on an OLED display.
What You'll Learn
- Implement a PID control algorithm for altitude stabilization using real-time pressure feedback.
- Interface a BMP280 temperature/pressure sensor with Arduino via I2C and interpret altitude data.
- Design and calibrate a servo-driven mechanical valve for precise helium release.
- Integrate an SD card module and DS3231 RTC for time-stamped data logging during flight tests.

Who This Kit Is For
This kit is built for advanced electronics learners: B.Tech ECE/EEE students prototyping altitude stabilization algorithms, Smart India Hackathon teams tackling atmospheric sensing challenges, and researchers at IITs, NITs, or VIT needing a reliable pressure-feedback controller. It's equally suited for serious makers exploring helium balloon hovercraft for scientific payloads.
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 kit for immediate AI guidance tied to this exact project. If you need human help, our WhatsApp support responds within hours.
Can I use this kit for scientific atmospheric data collection?
Absolutely. The DS3231 RTC time-stamps all SD card logs, and the BMP280 captures temperature and pressure, so you can profile vertical atmospheric layers or study local buoyancy changes.
Is the lithium battery safe for high-altitude flight?
Yes, the included 3.7V LiPo with TP4056 module has overcharge/discharge protection. For high-altitude missions, insulate the battery and monitor voltage via the OLED during ground tests.
How do I tune the PID controller for my specific balloon?
The AI companion provides a calibration routine: you'll run test inflations, log response curves, and adjust P, I, D gains based on your balloon's volume and payload weight, all with real-time graphing.
BMP280 pressure feedback controls servo valve releasing helium to maintain constant altitude hover.
