High-Altitude Balloon Telemetry Kit with Raspberry Pi Pico W & LoRa
High-Altitude Balloon Telemetry Kit 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.
Launch your own high-altitude balloon mission. This kit lets you assemble a compact telemetry module that reads temperature, humidity, pressure, and GPS coordinates, then beams them down via LoRa radio every 10 seconds - just like real atmospheric sounding systems.
What You'll Build
You'll build a lightweight, battery-powered sensor board that fits in a foam enclosure, ready to fly. Once assembled, the system transmits live location and environmental data to a ground receiver, giving you a real-time dashboard of the balloon's ascent through the atmosphere.
What You'll Learn
- How to interface BMP280, DHT22, and NEO-6M GPS with Raspberry Pi Pico W over I2C and UART
- Programming LoRa transmission with the RA-02 module - setting frequency, bandwidth, and spreading factor for long-range data
- Handling real-time GPS NMEA sentence parsing and converting coordinates into trackable position updates
- Designing a low-power system that runs for hours on a 3.7V LiPo battery and withstands flight conditions

Who This Kit Is For
This kit is built for advanced hobbyists and engineering students who want to explore high-altitude ballooning or long-range telemetry. It fits perfectly into B.Tech ECE/EEE atmospheric projects, Smart India Hackathon environmental monitoring challenges, or ATL Tinkering Lab modules for learners ready to move beyond basic sensors. IIT, NIT, VIT, and BITS students will find it a practical addition to their electronics lab.
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 companion with step-by-step guidance; you can also message us on WhatsApp for direct help from our team.
Do I need a separate receiver on the ground?
Yes, a compatible LoRa receiver module connected to another Pico or Arduino is required to capture the telemetry. We offer a Ground Station Kit separately, or you can set up your own with the same RA-02 module.
How high can the balloon fly with this payload?
The system is engineered to function up to 30 km altitude, though amateur flights are limited by regulations. The foam enclosure insulates the electronics against the extreme cold at high altitudes.
Can I change the data transmission interval?
The firmware is open-source; you can adjust the 10-second interval to any value you need, trading off between data resolution and battery endurance.
HVAC - Pico W reads BMP280 + DHT22 + GPS and transmits telemetry over LoRa every 10 seconds during balloon flight.
