To replace my old weatherstation, i orders some one-wire components from www.hobby-boards.com. A very popular one-wire sensor is the DS1820 temperature sensor. This sensor is on my sensor kit from hobby-boars, too. After building the sensor kit (Humidity/Temp/Solar Kit), i needed a good place for it outside. The sensor is placed in a case from hobbyboards. But i wanted some extra protection.
This small case is placed on the south-east side of my house an 1,5 m over the ground. The roof of the house prevent it from direct rain.
The sensor kit is connected over a default RJ-45 networkcable.
