High-Altitude Balloon Data Logger Kit - Log Pressure, Temperature, 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.

You are launching a payload to the edge of space. As your balloon ascends through the troposphere, atmospheric pressure collapses, temperature plummets to minus fifty degrees, and cosmic UV radiation spikes unfiltered by thickening air. This kit captures that complete environmental profile - pressure from the BMP280, temperature and humidity from the DHT22, UV intensity from the ML8511, and precise GPS coordinates from the NEO-6M - and logs every data point at 1Hz to an onboard SD card. The data you recover tells the story of the atmosphere's vertical structure, from humid surface layers to the dry, irradiated tropopause.

What You'll Build

You will assemble and solder a compact, insulated, self-powered data logger that rides inside a high-altitude balloon payload. The system wakes on launch, acquires synchronized sensor readings, tags each line with a UTC timestamp from the DS3231 RTC, and writes a CSV file to the MicroSD card. The foam enclosure and power filtering components ensure reliable operation during rapid temperature swings and low-pressure conditions. When you recover the payload, you will have a complete flight record ready for analysis in any spreadsheet or scientific plotting tool.

What You'll Learn

• Interfacing multiple I2C sensors on a single bus without address conflicts
• Designing a power management circuit with LiPo cell, charging module, and Schottky diodes for cold-soak resilience
• Parsing NMEA sentences from a GPS module to geo-tag each data row with latitude, longitude, and altitude
• Integrating a real-time clock for microsecond-accurate timestamps and implementing a finite state machine for 1Hz logging to FAT32

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

This kit serves B.Tech and M.Tech students in ECE, aerospace, and atmospheric science departments at IITs, NITs, and BITS who need reliable flight data loggers for stratospheric balloon experiments. Research labs conducting Smart India Hackathon projects on environmental monitoring or disaster telemetry will find the sensor suite immediately deployable. Experienced hobbyists and amateur radio operators coordinating high-altitude launches from ISRO-sounding rocket corridors or open rural ranges can use this as a turnkey payload core.
