The Ecowitt GW1103 weather station consists of the ultrasonic wind, temperature, humidity, solar radiation and UV sensor, the WiFi gateway (GW1100) and self emptying rain gauge making an advanced sensor set for those that want a modular weather station with full internet access.

The sonic anemometer sensor pack measures temperature, humidity, wind speed, wind direction, UV level and Solar intensity. 

The separate rain sensor measures rain fall and is self emptying for easy of use.

The GW1100 WiFi gateway is USB powered and also has builtin temperature, humidity and barometric pressure sensors for indoor readings.  The GW1100 gateway has these sensors on a wired probe so that they can be kept away from sources of heat which would skew readings.

This data, along with the outdoor sensor data is uploaded to the Ecowitt service via WiFi and is used to calculate rainfall rate, wind chill, dew point and heat index. All of this can be viewed on the App, or Ecowitt weather website.

You are not just limited to weather data on the Ecowitt weather site or App, you can share your data further afield with free access to The UK MetOffice WoW service, Weather Underground, WeatherCloud and your own web server.

Unlike some other stations, the Ecowitt GW1103 can be expanded with a variety of additional sensors which currently include:

  • 1 x WH57 lightning sensor
  • 1 x WH45 PM2.5/PM10/CO2/temperature and humidity all-in-1 sensor
  • Up to 8 WH31 multi-channel temperature and humidity sensors
  • Up to 8 WH51 soil moisture sensors
  • Up to 4 WH41/WH43 PM2.5 air quality sensors
  • Up to 4 WH55 Water leak sensors
  • Up to 8 WN34 Soil or Water temperature Sensors
  • Up to 8 WN35 leaf wetness sensors
  • Future sensors are also under development

All of these are available to view in the App, or online via and in the 3rd party services that support this sensor type.

The Ecowitt GW1103 includes the following items:

  • GW1100 WiFi gateway
  • USB power extension cable for GW1100 gateway
  • WS80 Ultrasonic 6-in-1 sensor array with revised design for improved accuracy during rainfall.
