Ecowitt WS3900 is a brand new 7.5-inch Wi-Fi LCD large screen weather station receiver. Supports monitoring indoor and out door conditions, has built-in temperature, humidity, barometric pressure sensors, and can connect almost all Ecowitt transmitters with the same RF frequency to use together, to get accurate weather data including wind speed, wind direction, rainfall, UV, solar radiation, outdoor temperature, outdoor humidity, dewpoint, feelslike,CO2, PM1.0, PM2.5, PM10 and more.
Meanwhile, it supports connecting IoT devices, such as WFC01andAC1100, to achieve smart control through the Ecowitt App, which is a powerful weather station receiver.
WS3900 supports connecting to a 2.4 GHz Wi-Fi network for viewing data from anywhere on your phone, tablet, and computer browser, all for free. Just so you know, the WS3900/WS3910 needs to be used with sensors to obtain outdoor weather data and is not a standalone product. The WS69 7-in-1 wireless solar powered weather sensor is included in this product.
