Outdoor Thermometer / Hygrometer

The placstic outdoor thermometer has gone with the wind some day. The double sided scotch became too weak on the sunlight to hold the thermometer on the window. Today anyone can look for the current weather conditions and forecast in the Internet, but sometimes the simple outdoor thermometer is more convenient. And the people that likes the arduino controller colld build own outdoor sensor! The algorithm of the thermometer is very simple. It has no menu or buttons, only display and sensors. Watchdog timer wakes up every 8 seconds, every 5-th time the information from the sensors read and print on the display. The external sensor installed to the small box to keep it dry in case of the rain. The external sensor is small and heats not much on the direct sunlight.”
