  • The Ecowitt HP2552 weather station consists of the standard anemometer, temperature, humidity, solar radiation and UV sensors, the self emptying rain gauge and large 7" TFT full colour screen making it an advanced weather station with full internet access.

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

    Two additional sensors are supplied, a rain sensor & separate temperature / humidity sensor. The rain sensor is self emptying for easy of use.

    The 7" high resolution TFT colour screen has a friendly & well-designed interface with two selectable backgrounds (dark or light). The console displays wind speed and direction, dew point, rainfall, indoor outdoor temperature and humidity, barometric pressure, moon phase, solar radiation and UV. There is also a full colour weather forecast function and you can also purchase a microSD memory card to store historical data. A 1GB card will store on average 10 years of data.

    This data, along with the outdoor sensor data is uploaded to the FREE 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 an iOS, Google App, or Ecowitt weather website in a browser.

    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 HP2552 can be expanded with a variety of additional sensors which currently include:

    • 1 x WH57 lightning sensor
    • 1 x WH45 indoor 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

The GW1000 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.
