Pi Pico W LoRa Weather Balloon Node
Build a Real-Time GPS Tracking Weather Balloon Node with Raspberry Pi Pico W & LoRa
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Send a Raspberry Pi Pico W to the edge of space. This kit guides you through building a fully self‑contained high‑altitude payload that reads temperature, humidity, barometric pressure, and GPS coordinates, then transmits the telemetry packet over LoRa every 10 seconds during balloon flight. You’ll assemble and program a rugged node that logs environmental data while tracking its own location—ideal for aerospace experiments, atmospheric research, or a definitive engineering capstone project.
What You'll Build
A compact, battery‑powered weather balloon node encased in protective foam. It continuously samples BMP280 pressure, DHT22 temperature/humidity, and NEO‑6M position, packages the readings, and shoots them via long‑range LoRa to a ground station. The finished device is flight‑ready: insulated against stratospheric cold, shock‑absorbent for landing, and programmed with periodic burst transmissions that conserve power while delivering real‑time data.
What You'll Learn
- Interfacing multiple I2C and UART sensors (BMP280, DHT22, GPS) with MicroPython on the Pico W
- Configuring and operating the RA‑02 LoRa module for 433 MHz long‑range communication
- Designing power‑efficient portable systems using a 3.7V LiPo cell and TP4056 charging module
- Structuring real‑time telemetry packets and timing transmissions for balloon ascent profiles

Who This Kit Is For
B.Tech ECE and aerospace engineering students tackling high‑altitude projects, Smart India Hackathon teams building disaster‑response telemetry, and ATL Tinkering Lab mentors guiding advanced experiments. It suits anyone who already knows basic electronics and wants to deploy a real LoRa‑based sensor network in a demanding field environment.
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 on the box, describe the issue, and receive component‑specific troubleshooting. You can also send photos via WhatsApp—our team responds within hours.
Can this node survive actual balloon flight conditions?
Yes. The foam enclosure insulates against cold and cushions landing forces. Every component has been tested in a thermal chamber down to -20°C, ensuring reliable operation up to the tropopause.
Do I need a separate LoRa ground receiver to see the data?
You will need a ground‑side LoRa receiver—another Pico with an RA‑02 module works perfectly. The AI companion includes a companion ground‑station code snippet and wiring diagram so you can set it up quickly.
Is soldering experience necessary for this kit?
Yes, soldering is required to assemble the sensor and LoRa module onto the prototype boards. The kit includes a soldering iron and solder wire, and the companion offers precise pad‑by‑pad guidance.
Pico W reads BMP280 + DHT22 + GPS and transmits telemetry over LoRa every 10 seconds during balloon flight.
