Build a High-Altitude Research Payload with Arduino Nano - Complete Weather Balloon Data Logger

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 a self-contained scientific instrument that rides a weather balloon to the edge of space and captures the environment every second. This Arduino Nano-based payload logs pressure, temperature, humidity, UV intensity, and precise GPS coordinates onto an SD card - creating a vertical profile you can analyse after recovery. It's built for the cold, thin air and rough parachuting descent that real high-altitude flights demand, giving you a complete data set from ground to burst and back.

What You'll Build

A compact, insulated data logger that runs on a single LiPo cell and records all five environmental parameters at 1 Hz with an RTC timestamp. You'll solder the sensor modules, write the logging sketch, and package the electronics inside the foam enclosure to withstand the rapid temperature drops and near-vacuum conditions of the upper troposphere. The result is a payload ready to be tucked into a balloon train, delivering a CSV file you can visualise and share after landing.

What You'll Learn

• Soldering and wiring a multi-sensor circuit with I2C, one-wire, and serial peripherals
• Implementing reliable SD card data logging with error handling and real-time clock stamps
• Managing power for battery-operated payloads with diode protection and efficient sleep-wake cycles
• Packaging electronics inside foam insulation for sub-zero temperatures and low-pressure operation

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

This advanced kit is made for aerospace engineering students at IIT, NIT, VIT, or BITS Pilani working on high-altitude balloon experiments, atmospheric researchers at IISc or other institutions conducting upper-air surveys, and experienced makers who have already built mid-level electronics and want to capture their own environmental data. If you're participating in a national competition like Smart India Hackathon or developing a CanSat-like balloon payload for a university project, this system delivers the core logging backbone you need.

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.
