ATL Pressure and Altitude Lab Kit
ATL Pressure & Altitude Kit: Measure Floor Height with BMP390 Arduino
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Walk from the ground floor to the first floor and watch the OLED display instantly calculate your vertical rise. The BMP390 Precision Barometer catches air pressure changes as small as a few pascals, converting them into altitude readings accurate enough to detect the height of a single staircase. This ATL lab kit turns a school building into a living experiment — no lab bench required.
What You'll Build
You will assemble a portable altitude monitor powered by an Arduino Nano. Carry it to different floors, and the OLED screen will show real‑time height changes relative to your starting point. Five reusable data log sheets are included so you can record pressure and altitude readings, then graph the relationship between atmospheric pressure and elevation.
What You'll Learn
- How barometric pressure decreases predictably with altitude
- Wire and communicate with an I2C sensor (BMP390) and OLED display
- Program the Arduino Nano to read pressure, compute altitude, and update the display
- Collect, organize, and plot experimental data on log sheets

Who This Kit Is For
Built for CBSE Class 6–10 students exploring real-world physics, ATL Tinkering Lab facilitators leading hands‑on measurement activities, and science hobby clubs that want a reliable sensor experiment. B.Tech first‑year labs in Indian universities also use it to teach sensor interfacing and data logging in a single practical session.
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 access the AI companion, which guides you step by step. You can also send a WhatsApp message for direct support from our team.
How does the BMP390 measure altitude without GPS?
The BMP390 senses atmospheric pressure. As you go higher, pressure drops, and the sensor converts that drop into an altitude reading using a standard pressure‑altitude formula calibrated to your starting floor.
Can I log data to a computer instead of the paper sheets?
The kit includes printable log sheets for immediate plotting, but the Arduino Nano also sends serial data over USB. You can open the serial monitor or use a simple Python script to capture readings on any PC.
Is this kit suitable for a science exhibition or ATL project display?
Absolutely. The live OLED display and the physical act of walking between floors make it an engaging, demonstrable project that clearly shows the science of pressure and altitude.
BMP390 barometer on Arduino measures altitude change when carried to different floors — tracks pressure vs height.
