Atmospheric Pressure vs Altitude Study Kit with Arduino Nano + BMP280
Build an Atmospheric Pressure vs Altitude Data Logger with Arduino Nano & Dual BMP280
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
With this kit, you'll build a compact data logger that deploys on a drone or weather balloon, capturing precise pressure and temperature readings from two BMP280 sensors every second. Back on the ground, you'll plot the pressure-altitude relationship using real data — exactly how meteorologists and drone engineers analyze atmospheric layers.
What You'll Build
A rugged, battery-powered logging system that records dual-sensor pressure data to a microSD card. After a flight, you can retrieve a CSV file, clean it, and generate a smooth pressure-altitude curve. The onboard OLED shows live pressure and a timestamp, so you know the system is active during launch.
What You'll Learn
- Writing multi-sensor I2C communication code using a TCA9548A multiplexer
- Timestamping sensor readings with a DS3231 real-time clock for synchronized logs
- Managing power with a LiPo battery, TP4056 charger, and low-power Arduino Nano
- Plotting atmospheric pressure vs. altitude with Python or MATLAB from SD card data

Who This Kit Is For
This kit is built for B.Tech ECE/EEE students tackling atmospheric sensing projects, Smart India Hackathon teams designing drone-based environment monitors, and college clubs preparing payloads for high-altitude balloon experiments. It's also a favourite at IIT, NIT, VIT, and BITS Pilani for capstone projects in wireless sensor networks and data acquisition.
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 to chat with the AI companion, which knows the schematic and code line by line. If you need a human, WhatsApp us and we'll debug together.
Can I fly this on a drone without interference?
The board is lightweight (under 80 g with battery) and uses a shielded I2C mux, so it won't disrupt GPS or RC signals. Mount it firmly and route antennas away.
Do I need to code from scratch?
No, we provide fully commented Arduino sketches and a Python plotting script. You can tweak sampling rates, sensor offsets, or display formats right away.
What does the pressure-altitude plot look like after a flight?
You'll get a CSV with timestamps and dual‑BMP280 pressures. The Python script generates a smooth curve that clearly shows the exponential pressure drop with altitude — a classic atmospheric profile.
BMP280 on a drone or balloon logs pressure every second. Plots pressure-altitude relationship in real data.
