Ecowitt WS3900 Weather Station with W69 7-in-1 Outdoor Sensor

A complete, ready-to-go weather station — the WS3900 Wi-Fi console paired with Ecowitt's 7-in-1 outdoor sensor, so you're measuring your own backyard conditions straight out of the box.

The large 7.5" console puts everything on one clear LCD: outdoor and indoor conditions, wind, rainfall, pressure trends, UV, and a local forecast — while logging it all to the free Ecowitt cloud so you can check home from anywhere on your phone.

Out in the weather, the WS69 sensor array tracks seven measurements at once: rainfall, wind speed, wind direction, temperature, humidity, solar radiation and UV index. It's solar-powered with battery backup, so once it's mounted on a pole and paired, it just keeps reporting — no mains power, no regular battery swaps. The complete mounting kit is included.

Whether you're a grower keeping an eye on frost, rainfall and UV, a boatie or pilot tracking wind, or simply someone who likes knowing exactly what's happening at home, this station turns your local conditions into data you can actually use — and expand on later with Ecowitt's wide range of add-on sensors.
