[wxsig] Family Codes and ds2438

[William Beals]

Michael and Pedro:

Cool on getting things working.  

Pedro:  The nice part about getting into the programming is you can go fiddle with the look and feel of the device.  If you put all the Spanish support in a separate text file, could it be added to the overall code offering?

Hi Michael:

I can only tell about what i have found.

Humidity: I have build my own sensor with a ds2438's clone (buyed from
ebay) - if you can get an original Dallas 2438 would be better, Humidity
sensor is is a HIH-4000-004, buyed from mouser, building is
straightforward, just the ds2438, Humidity sensor, a 7805 voltage
regulator, and a resistor.

Hard part is to change code to adquire data from the clone, but it is
solved and now very simple.

For now it works, now I have to tune it and adjust, when it is ok, I
will make a small pcb, an outdoor shield, etc.

Best regards.

Pedro.
