Weather Trend Kit with Arduino Uno & BMP280 - Predict Rain or Fair Weather with Pressure Trends

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

What if your Arduino could look at pressure trends and tell you whether to carry an umbrella - before the weather apps update? With this kit, you'll build a standalone device that takes a reading from the BMP280 sensor every 10 minutes, compares it to recent history, and shows a sun or rain icon on the OLED screen. No internet, no subscription, just physics.

What You'll Build

You'll assemble a weather indicator that uses the BMP280 to sample atmospheric pressure, the DS3231 RTC to keep precise 10-minute intervals, and the 0.96-inch OLED to show a clear sun (rising pressure, fair weather) or rain cloud (falling pressure, rain likely). The trend logic runs entirely on the Arduino Uno, making this a self-contained predictor you can mount on a wall or carry to school.

What You'll Learn

• Interface I2C sensors (BMP280 and OLED) using the Wire library
• Implement a trend-detection algorithm by comparing rolling pressure averages
• Use a DS3231 RTC module to trigger periodic sensor reads without delay loops
• Troubleshoot noisy signals with decoupling capacitors on a breadboard

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

If you're a CBSE Class 11-12 student looking for a unique physics-in-action project, or a B.Tech ECE/EEE first-year building a mini-project, this kit delivers a complete experience. It is also ideal for ATL Tinkering Labs and Smart India Hackathon participants who need a rapid prototype for weather-based IoT ideas. The build fits neatly into a 4-hour lab session and teaches engineering thinking through real sensor data.

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.
