## Summary description

## Long description

The TFA-Dostmann Sun 2 Black LED is a compact indoor/outdoor thermometer and hygrometer with a colour-illuminated display that gives a clear overview of current weather information. An integrated electronic barometer measures air pressure and the device shows a simple weather forecast with sun, cloud or rain symbols above a colourful landscape. Outdoor temperature and humidity are provided by a dedicated wireless transmitter; daily maximum and minimum outdoor temperatures are permanently shown. Indoor temperature and humidity are displayed with a comfort-level (smiley) indicator. Time and date are received by radio; the unit can stand on a table or be wall-mounted. A mains adapter for the base station is included, and up to three additional wireless transmitters can be paired for monitoring other locations.
Advantages
The colour LED display provides readable weather information and adjustable brightness with four levels plus an automatic night dimming period. Wireless transmission supports up to three outdoor transmitters (range up to 100 m) so you can monitor multiple locations such as garden, basement or children's room. The station permanently stores and displays daily max/min outdoor temperatures including time and date of recording, and shows dew point. Integrated radio-controlled clock with weekday and date (6 languages) and an alarm with snooze function add everyday convenience.
Suitable for
