The WN38 Black Globe Thermometer measures and displays the black globe temperature only, which can be viewed on the LCD screen or through the Ecowitt or WS View Plus app.
The WN38 is a professional, wireless black globe temperature sensor designed for long-term outdoor monitoring. Its core value lies in accurately measuring "perceived temperature," and based on this, combining with your weather station data to provide the WBGT (Wet Bulb Globe Temperature) index, which directly evaluates the heat stress imposed by the environment on the human body.
To display WBGT (Wet Bulb Globe Temperature) data in the app, the WN38 must be used together with an Ecowitt outdoor temperature and humidity sensor from either an outdoor array (WS69, WS90 etc) or the WN32 outdoor sensor.
The collected data can be transmitted via an Ecowitt Wi-Fi Gateway or displayed on a compatible receiver console (both sold separately). Once Wi-Fi configuration is completed, data can be viewed in real time through the Ecowitt app, WS View Plus app, or on the receiver console.
Unlike some other brands, the Ecowitt WN38 can be used with a variety of products, click here to view the latest Ecowitt sensor matrix.

Once again first class service from weather Spares.
The WN38 is very well made and easy to set up, but remember to clear the cache in the settings on the
Ecowitt app otherwise the data will not be seen on the data screen. This sensor is a good addition to my station
setup.
