BMP280 Barometric Pressure Starter Kit — Build a Real-Time Altitude Monitor with Arduino Uno

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 device that reads barometric pressure and temperature over I2C from the BMP280 sensor, then converts pressure to an accurate altitude estimate — just like a digital altimeter. The result appears live on a crisp 0.96-inch OLED, turning raw environmental data into a practical altitude monitor you can carry anywhere.

What You'll Build

You will assemble a fully functional barometric altimeter and thermometer on a solderless breadboard. The Arduino Uno reads the BMP280’s pressure and temperature, applies the barometric formula to compute altitude above sea level, and displays the values on the OLED in real time. You’ll have a portable science gadget that demonstrates atmospheric physics in your hands.

What You'll Learn

• Interface I2C sensors with Arduino, using the Wire library to talk to the BMP280 and OLED
• Read barometric pressure in Pascals and temperature in Celsius, then convert to user-friendly units
• Estimate altitude using the international barometric formula and calibrate for local sea-level pressure
• Display multiple sensor readings on a 0.96-inch I2C OLED screen, managing layout and refresh
