Wireless Weather Station - WLWSTAT1
Wireless Weather Station with Rain Gauge and Forecasting
A feature-packed weather station for the enthusiast forecaster. The outdoor sensors will monitor up to 10 key weather parameters and will transmit up to 150 metres to the indoor base station to keep you updated on current and future weather conditions. This station will measure indoor/outdoor temperature, relative humidity, rain, wind speed, wind chill, dew point, barometric pressure and also displays the date and time. All minimum and maximum values with the date and time it was recorded will be stored for your reference on an easy to read display screen.
The unit includes a weather tendency indicator that will display 1 of 4 icons (sunny, cloudy, partly cloudy or rainy) indicating the likelihood of future weather. When the sensors detect a pressure fall of 3 - 9hPa, a storm warning will be displayed on-screen. The storm threshold value is user adjustable. Alarms for certain weather conditions can be programmed to alert you to potential atmospheric hazards. If you enjoy outdoor activities that require specific weather conditions the alarm feature is a great tool to give you accurate information on potential trouble.
