## Long description

The TFA-Dostmann Casa Black LCD Battery Indoor Outdoor Thermometer Hygrometer (MPN 35.1135.02) displays current weather information with intuitive weather icons and provides time synchronized via the DCF77 atomic-clock signal.

The device runs on AA batteries and features an LCD with backlight, making readings easy to see in different lighting conditions.
