Pi Pico Barometric Altimeter
Pi Pico Barometric Altimeter Kit: Wearable Altitude Tracker for Hiking and Rockets
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Ever wondered how high you climbed on a trek or how far your model rocket flew? This kit lets you build a real-time altimeter that displays altitude on a tiny OLED screen. Powered by a Raspberry Pi Pico and a BMP280 barometric sensor, the project slips into a wearable ABS enclosure — perfect for strapping to a backpack, wrist, or rocket payload bay.
What You'll Build
You'll assemble a compact altitude tracker that reads air pressure, converts it to height above sea level, and shows the reading instantly. The enclosure keeps components secure, and a 500 mAh LiPo with a charging module gives you hours of portable use. Pair it with a hike to log elevation gain, or launch it inside a model rocket to capture apogee data.
What You'll Learn
- Reading barometric pressure from the BMP280 sensor over I2C
- Interfacing a 0.96-inch OLED display with the Raspberry Pi Pico
- Soldering components onto a PCB prototype board and assembling a wearable device
- Programming altitude calculations in MicroPython from raw pressure data

Who This Kit Is For
Young makers and students will love this project. CBSE Class 11-12 physics enthusiasts can explore pressure‑altitude relationships, while B.Tech ECE/EEE first‑years gain hands‑on sensor experience. It’s also a hit in ATL tinkering labs and Smart India Hackathon teams working on outdoor‑tech prototypes. With adult supervision, even 10‑year‑olds can solder and see their altitude on screen.
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 launch the AI companion, which walks you through every solder joint and code line. Our team is also a WhatsApp message away if you need extra help.
Do I need prior soldering experience?
Not at all. The included soldering iron and simple through‑hole joints make learning easy. Many first‑time builders complete this kit with guidance from the AI companion.
Can this altimeter be used in a model rocket?
Yes — the assembled module weighs under 50 grams and fits most payload bays. Secure it with foam and it will capture altitude during flight. Data logging can be added with minor code tweaks.
How accurate are the altitude readings?
The BMP280 measures pressure changes equivalent to about 1‑meter altitude resolution. For best results, calibrate against a known elevation before each use, which the companion guides you through.
BMP280 on Pico shows altitude in a wearable enclosure. Good for hiking and model rocketry.
