Greenhouse Pressure Monitor Kit v2
Arduino-Powered Weather Balloon Data Logger – Greenhouse Pressure Monitor Kit v2
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 environmental monitoring payload aboard a weather balloon to profile atmospheric pressure, temperature, and humidity from ground to near-space. This advanced kit integrates precision sensors with GPS tracking and onboard logging, building a robust data recorder that withstands rapid ascent and temperature swings. Ideal for university weather projects, Smart India Hackathon challenges, or serious DIY atmospheric science.
What You'll Build
A self-contained payload that logs BMP280 pressure, SHT31 temperature/humidity, and GPS coordinates to a microSD card during a 2–3 hour balloon flight. The thermal foam housing ensures stable readings despite external temperatures dropping to -50°C.
What You'll Learn
- Soldering SMD and through-hole components onto a prototype PCB
- Configuring I2C sensors (BMP280, SHT31) and parsing GPS NMEA data with Arduino
- Designing a power system with LiPo battery and TP4056 charging module
- Implementing fail-safe logging with DS3231 RTC timestamps

Why Buy This Kit Instead of Sourcing Parts Separately
| Factor | Sourcing Separately | Compoden Kit |
|---|---|---|
| Compatibility checks | You verify every part; BMP280/SHT31 address conflicts, GPS baud rate mismatches | Pre-tested as a system; I2C addresses unique, GPS configured to 9600 bps |
| Build support | Forums and scattered tutorials for balloon payloads | AI companion trained on this exact project with flight-proven wiring diagram |
| Time to first working build | Days of debugging sensor noise and SD card write errors | Hours, with step-by-step guidance from soldering to first successful log |
| Shipping coordination | Multiple sellers, multiple delays for foam enclosure and PCB boards | One shipment from Bengaluru in 3-5 days, including soldering iron |
Who This Kit Is For
B.Tech ECE/EEE students building an advanced instrumentation project, Smart India Hackathon teams tackling environmental monitoring tracks, and weather balloon club members at NITs, IITs, VIT, or BITS Pilani. The build requires prior experience with Arduino programming and soldering.
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 access the AI build companion for real-time troubleshooting. For deeper issues, our WhatsApp support (Mon-Sat) is backed by engineers who've flown this exact payload.
Does this kit include everything to launch a weather balloon?
No, you’ll need to source the balloon, helium, parachute, and regulatory permissions separately. This kit provides the complete scientific payload.
Can I modify the code to add a camera or other sensors?
Yes, the Arduino Nano has 6 spare digital pins and the AI companion includes hints for expanding the payload. The foam enclosure can be reshaped to fit additional modules.
What altitude range can this payload survive?
The foam housing protects the electronics down to -40°C ambient and 10 hPa pressure. The BMP280 measures pressure up to 30 km altitude; the GPS may lose lock above 18 km.
