Full Davis-Style Home Weather Station
Arduino Mega Weather Station Kit: Complete Davis-Style Home Weather Logger
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Step into professional-grade environmental monitoring with a full Davis-style weather station that rivals commercial units. By integrating wind speed, direction, rainfall, temperature, humidity and barometric pressure into one Arduino Mega–powered data logger, you’ll capture hyperlocal weather trends right at home — ideal for agriculture analytics, Smart India Hackathon projects, or simply understanding your microclimate like a meteorologist.
What You'll Build
You'll assemble a self-contained weather station that reads wind speed via a hall-effect anemometer, detects rain with a tipping-bucket gauge driven by reed switches, and logs temperature, humidity, and pressure from DHT22 and BMP280 sensors. An OLED screen shows real-time readings, while an RTC-stamped MicroSD card stores every data point for later graphing or analysis.
What You'll Learn
- Pulse counting and debouncing for accurate wind speed and rain gauge inputs using hall and reed switches
- Multi-sensor fusion: interfacing DHT22, BMP280, and multiple digital signals without conflicts
- Time-series data logging with DS3231 RTC and SD card module for long-term environmental records
- Designing a modular PCB prototype layout to reduce noise in analog and digital lines

Who This Kit Is For
B.Tech ECE/EEE students building a capstone project that demonstrates sensor integration and data logging will find this kit ready for Smart India Hackathon submissions. CBSE Class 12 students with Arduino experience can use it to set up a live weather station for ATL Tinkering Labs. Agriculture researchers and DIY hobbyists aiming for Davis-like accuracy without the cost get a complete reference design.
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?
The AI companion walks you through each wiring step and code block; just scan the QR code. If that doesn’t help, our WhatsApp support replies within a few hours.
Can I modify the code to connect to IoT platforms?
Yes, the Arduino Mega has multiple UARTs. You can add an ESP8266 or GSM module and adapt the logging code — our AI companion can suggest integration steps for ThingSpeak or Blynk.
How accurate are the wind and rain measurements?
The hall-effect sensors deliver pulse counts with ±2% typical error when properly calibrated. The kit includes a calibration guide for the anemometer and rain gauge to match local conditions.
Can I run this station on solar power?
With an external power management board (not included), the 9V battery snap can connect to a regulated solar supply. The Mega’s low-power sleep modes can be enabled for off-grid use.
Wind speed, wind direction, rain gauge, temperature, humidity and pressure all integrated into one data logger.
