Water temperature mk2

The latest activity have been to rewrite parts of the code to use DS18b20 instead of the DHT22 in mk2. At the hardware level I've added a proper antenna to see what range we can get.

For test 2 the probe was placed in the office-window of a friend close to 9km away, this did not work and i saw no updates at the base station. So the plan is to find a location somewhere between 3km and 9km away. 

The first tests was to place the probe at a distance but still in view from the base station. 

For test 1 the probe was placed in a flowerpot at a colleagues house about 3km away and it worked flawlessly.
