Advanced METAR Weather Station Kit with ESP32
Automated METAR Generator Kit with ESP32: Publish ICAO Weather Reports
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Turn an ESP32 and a suite of environmental sensors into a self-contained weather station that speaks aviation's language. This kit assembles a solar-powered field unit that automatically compiles ICAO-formatted METAR messages - temperature, pressure, wind, rain, UV - every 30 minutes and pushes them live to any web endpoint. Whether you operate a private airstrip, run drone logistics, or manage precision agriculture, you get a deployable station that feeds usable, time-stamped weather intelligence to your dashboard or the aviation ecosystem.
What You'll Build
You will assemble a fully outdoor-rated weather station in a waterproof enclosure. Once programmed, the ESP32 reads DHT22, BMP280, UV, Hall-effect wind sensors, and a rain gauge, composes an ICAO METAR string with QNH, wind direction/speed, visibility codes, and weather phenomena, then posts it over Wi-Fi to an endpoint of your choice - think Windy, Open-Meteo, or your own server. The 6V solar panel and TP4056 charge controller keep a Li-ion battery topped up through the LM2596 buck converter, so the station runs unattended. A microSD module logs all local data, while the 0.96-inch OLED gives you at-a-glance readings when you're on site.
What You'll Learn
- Interfacing DHT22, BMP280, ML8511 UV, Hall, and rain sensors with ESP32 over I2C and GPIO
- Constructing ICAO METAR strings with mandatory fields including QNH, wind, visibility, and weather codes
- Scheduling periodic data collection and HTTP POST requests with a DS3231 RTC for reliable offline timing
- Assembling a solar-powered system with a Li-ion battery, TP4056 charger, and LM2596 buck converter for continuous outdoor operation

Who This Kit Is For
This kit targets advanced makers, especially B.Tech Aerospace or ECE students using drones and UAVs, private airstrip operators who need to feed METAR data to flight planning apps, and researchers deploying agrometeorology stations in remote farmlands. It's equally relevant for Smart India Hackathon teams building climate-resilience prototypes and ATL tinkering lab mentors introducing formal weather reporting to older students.
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 included in the box to start a conversation with the AI companion trained on this exact METAR generator. If you need a human touch, our team responds on WhatsApp within a few hours.
Does the station work without Wi-Fi or a SIM card?
The ESP32 posts data over Wi-Fi. The 433 MHz antenna is for receiving data from external wireless wind-vane sensors (magnet assembly not included). You can add an LTE module to the prototype board's serial header if you want cellular uplink in remote locations.
How do I assign an ICAO station identifier?
You enter a four-character station ID in the firmware. We provide instructions for testing with a dummy code, or you can register a formal identifier if you are operating at a recognised aerodrome; the kit is ready for official ID insertion.
Is the build suitable for permanent outdoor deployment?
Yes. The waterproof enclosure and solar power system are designed for continuous outdoor use. You will need to construct the wind vane/anemometer with the two Hall sensors and mount the rain sensor; the kit includes prototype boards and a soldering iron to complete the sensor assembly.
Assembles ICAO METAR coded weather report every 30 min from local sensors. Posts to web endpoint.
