Ecowitt WN32 Primary Temperature & Humidity Sensor

The WN32A (WH32) sensor is used as your primary source of outdoor temperature & humidity readings which will upload to online services including MetOffice WoW & WeatherUnderground along with the Ecowitt network.

If used with a multi-sensor array, this sensor will override the built in temperature & humidity readings of these (5-in-1, 7-in-1, WS80, WS90, WittBoy models etc). Ideal if you wish to separate your temperature and humidity readings from the main array, but not if you wish to have an additional set of readings; use the WN31 instead.

Before purchase, please be aware of the following:

• Only one WN32A (WH32) sensor or multi-sensor array can be used with the gateway or console as your primary device for reporting temperature & humidity to online services
• If a WN32 sensor is used alongside a multi-sensors array then only the WN32 readings will be displayed
• You cannot use this as an additional sensor, please use the WN31 multichannel sensor
• You may need to enable the T&H sensor option on your console / gateway before readings are visible
