Aercus Instruments WeatherMaster - Advanced Weather Station with WiFi and optional extra sensors

The Aercus Instruments WeatherMaster is the latest in the Aercus range of fully-featured weather stations. The all in one outdoor sensor array measures temperature, humidity, rainfall, solar radiation, UV Index, wind speed and wind direction. In addition, the indoor sensor measures your indoor temperature, humidity and atmospheric pressure.

The WeatherMaster, is the one of most feature-rich and advanced mid-range station in our region for personal or professional use. Includes support for several additional sensors, and WiFi upload to variety of popular community sites.

Extra sensors:

• Add up to 8 indoor temperature and humidity sensors (one included), if you would like to monitor other rooms, such as your cellar, nursery or greenhouse. 
• Add up to 8 WH51 soil moisture sensors, allowing you to monitor different regions of your garden, crops or pasture.
• Add the Aercus Instruments Outdoor PM2.5 Air Quality sensor.

Features:

• Large TFT colour screen with light and dark themes and adjustable brightness
• Internet upload to Weather Underground, WOW (Met Office/Met Service/BoM), Ecowitt, WeatherCloud or custom servers
• 2.4GHz WiFi
