Our take on the WS3800 / WS3900 Wi-Fi Weather Station with 7.5'' LCD Display and 7-in-1 Outdoor Sensor Array

The WS3800 is a Wi-Fi weather station built around a 7.5-inch LCD console and a 7-in-1 outdoor sensor array that measures wind speed and direction, temperature, humidity, rainfall, UV and light. The console also has its own indoor temperature, humidity and barometric pressure sensors, plus a forecast, moon phase, sunrise/sunset and max/min records. It runs on DC power, with AA batteries only as a short-term backup, so plan on an outlet. It suits people who want a large, readable home display and phone access to their own backyard readings, and it competes with stations like the Ambient Weather WS-2902 and Davis Vantage Vue on sensor count rather than build quality.

About the WS3800 / WS3900 Wi-Fi Weather Station with 7.5'' LCD Display and 7-in-1 Outdoor Sensor Array

This Wi-Fi weather station pairs a 7.5-inch LCD display console with the WS69 7-in-1 outdoor sensor array. The console has a built-in temperature and humidity sensor and a barometric pressure sensor. It also shows the calendar, date, time, moon phase, sunrise, sunset, and an alarm with snooze.

The WS69 outdoor sensor measures temperature, humidity, wind speed, wind direction, rainfall, UV, and solar radiation. It runs on solar power or battery power. The console forecasts sunny, partly cloudy, cloudy, rainy, stormy, snowy, and storm snowy conditions. It records daily maximum and minimum values and has a reset function to clear them.

The console can hang on a wall or stand on its own. Data is stored on the Ecowitt server and can also be uploaded to third-party platforms. Optional sensors and IoT devices, sold separately, can be added.
