Ambient Weather WS-5000 vs Ecowitt WS3900 Weather Station

Buy the Ambient Weather WS-5000 if you want the more accurate, lower-maintenance instrument: its ultrasonic anemometer has no cups or vanes to wear out or ice up, and its pagoda radiation shield gives better temperature and humidity readings. The Ecowitt WS3900 is the better pick for a large, easy-to-read indoor display and a conventional sensor array that many owners find simple to set up. Both report the same core set of readings, but the WS-5000 is the step up in sensor design and build.

• Choose the Ambient Weather WS-5000 if you want a no-moving-parts ultrasonic wind sensor and more accurate temperature and humidity readings.
• Choose the Ecowitt WS3900 if a big 7.5-inch indoor display and a familiar cup-and-vane sensor array matter more to you than ultrasonic wind sensing.
