High-Altitude Balloon Data Logger Kit
High-Altitude Balloon Data Logger Kit — Capture Pressure, Temp, GPS & UV with Arduino Nano
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Launch your own stratospheric mission with a payload that logs pressure, temperature, humidity, GPS coordinates and UV radiation every second to an onboard SD card. This kit from Compoden brings together every sensor, power module and structural component needed to build a flight-ready data recorder for high-altitude balloon projects. Designed for engineering students, research hobbyists and weather enthusiasts, the assembled logger withstands the -50°C cold and near-vacuum of the upper atmosphere inside a foam-insulated enclosure.
What You'll Build
You'll create a self-contained payload box that rides beneath a weather balloon up to 30 km altitude. The Arduino Nano reads BMP280 pressure/temperature, DHT22 humidity, ML8511 UV intensity and NEO-6M GPS location, stamping each record with a DS3231 real-time clock. All sensor data is written to a MicroSD card at 1 Hz, giving you a complete atmospheric profile from the ground to the burst altitude and back down. The lithium-polymer battery and TP4056 charging circuit keep the system running for a full 3–4 hour flight.
What You'll Learn
- Interfacing multiple I²C and SPI sensors with an Arduino Nano
- Parsing NMEA sentences from a GPS module and timestamping logs with an RTC
- Managing LiPo battery power with a TP4056 charger and 1N5819 diodes for safe discharge
- Writing sensor data to a MicroSD card in CSV format for later analysis in Excel or Python

Who This Kit Is For
B.Tech ECE/EEE students working on final-year atmospheric or IoT projects will find this kit aligns with curriculum requirements for sensor integration and embedded systems. It is also ideal for Smart India Hackathon participants needing a ready-to-fly environmental payload. Amateur radio clubs, weather enthusiasts and researchers across IITs, NITs or VIT will appreciate the complete, solder-included package that eliminates the hassle of hunting for rare sensor modules one by one.
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 inside the box to access the AI build companion that guides you through wiring and code for this specific payload. You can also send photos or questions via WhatsApp and receive human support within hours.
Do I need any permissions to launch a weather balloon with this payload in India?
Yes, you must obtain clearance from local aviation authorities and the Airports Authority of India. The kit documentation includes pointers on how to file a NOTAM and coordinate with ATC. The payload itself weighs under 500 g, which simplifies the process.
How long will the battery last during a real flight?
The 1000 mAh LiPo powers the Nano and all sensors for approximately 3.5 hours of continuous 1 Hz logging, sufficient for a typical ascent to 30 km and parachute descent. The TP4056 module lets you recharge the battery via USB between flights.
Will the foam enclosure really protect against stratospheric temperatures?
The closed-cell foam insulation slows heat loss, allowing the internal electronics to stay above -20°C even when outside air drops to -50°C. We've tested similar configurations on multiple flights over Karnataka; the payload kept logging reliably throughout the mission.
Infant Care — Arduino Nano logs pressure, temperature, humidity, GPS coordinates and UV at 1Hz to SD card during high-altitude balloon flight.
