Arduino Outdoor Weather Monitor Kit - Log Temp, Humidity, Pressure & Light with OLED Display
Arduino Outdoor Weather Station: Real-Time Data Logger with DHT22, BMP280, LDR and OLED Display
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Ready to capture environmental data with lab-grade accuracy? This kit lets you build a complete outdoor monitoring tool that records temperature, humidity, barometric pressure, and light intensity onto an SD card, stamped with real-time clock timestamps. An OLED screen shows live readings at a glance - perfect for field deployment, research logging, or an advanced college project that stands out.
What You'll Build
You'll assemble a sturdy, battery-powered Arduino station that reads DHT22, BMP280, and two LDR sensors every second, writes the values to a text file on the microSD card with date and time from the DS3231 RTC, and refreshes the 0.96-inch OLED display. The whole setup fits on a prototype PCB board, ready to be mounted inside a weather-proof enclosure for long-term outdoor use.
What You'll Learn
- Interface I2C-based sensors (BMP280, OLED) and digital one-wire DHT22 with precise library calibration
- Implement circular buffer logging to SD card with error recovery and timestamp synchronization from DS3231
- Design low-power battery management for a portable field station with 9V supply
- Create real-time display updates with minimal flicker on SSD1306 OLED using Adafruit GFX

Who This Kit Is For
Built for final-year B.Tech ECE/EEE students tackling weather-monitoring capstone projects, Smart India Hackathon teams needing robust environmental data collection, and CBSE Class 12 science stream students preparing advanced physics investigatory projects. Also used by ATL Tinkering Lab mentors for teaching data logging concepts and by research scholars building low-cost outdoor sensor arrays.
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 chat with the AI companion trained on this project - it can debug wiring, code, and sensor calibration. Or message us on WhatsApp for direct human help within 24 hours.
Can I leave this station outdoors for long-term monitoring?
Yes, with a waterproof enclosure (not included), the DHT22 and BMP280 are rated for outdoor use. The SD card logs continuously; swap the 9V battery for a solar panel and lithium cell to run for weeks without maintenance.
Can I modify the code to upload data to the cloud?
Absolutely. The kit is Arduino-based, so you can add a Wi-Fi module (like ESP8266) and modify the code to push data to ThingSpeak, Blynk, or a custom MQTT broker. Our AI companion can suggest code snippets for cloud integration.
Does this kit include a case or enclosure to protect it from rain?
No, the kit contains all electronic components on a PCB prototype board. You'll need to build or buy an IP65 enclosure separately for protection. We provide a drilling guide for cable glands to pass sensor probes outside while keeping the electronics dry inside.
