TK has come to us with his simple Arduino based DIY weather station. His easy to follow instructions will have you up and running in no time.

A DHT11 monitors the temperature and humidity. A charge circuit and lithium battery provide power. Finally, the watch displays the date, time, and other data with an LCD from a Nokia 5110.

The LCD panel can be used with any Arduino-compatible board, so it can be useful in a whole host of projects. Stick around to see a simple demo of the board in use.
