Arduino Weather Station Kit: Display Temperature, Humidity & Pressure with Trend Arrows on OLED

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

Transform a handful of components into a fully functional weather station that goes beyond simple numbers. This kit lets you measure ambient temperature, relative humidity, and barometric pressure, then displays them on a crisp OLED screen along with dynamic up/down trend arrows. Whether you're preparing for a CBSE electronics project, a Smart India Hackathon prototype, or just satisfying your curiosity about the microclimate around you, this intermediate build gives you real meteorological insight.

What You'll Build

You'll assemble a self-contained monitoring station that reads DHT22 and BMP280 sensor data, processes it through an Arduino Uno, and outputs current readings with trend indicators on a 0.96‑inch OLED. The active buzzer alerts you to threshold breaches, while two tactile buttons let you cycle through display modes or reset statistics. At the end, you have a portable weather dashboard you can place on a desk or mount outdoors in a shaded enclosure.

What You'll Learn

• Interface DHT22 and BMP280 sensors with Arduino using I2C and one‑wire protocols
• Compute rolling averages to generate trend arrows for temperature, humidity, and pressure
• Drive an SSD1306 OLED display with graphical symbols and real‑time text
• Integrate user input with tactile buttons to switch parameters or dismiss alarms

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

If you're a CBSE Class 11–12 student preparing a functional science exhibit, a B.Tech ECE or EEE undergrad at an Indian university exploring IoT, or a participant in the Smart India Hackathon, this kit bridges theory and practice. ATL Tinkering Lab mentors and hobbyists from colleges like VIT, NIT, or BITS will also find it an ideal weekend build with real environmental data to collect and analyze.

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.
