Playing with bits of wire.SD card and RTC tested.
probably will use Lady Ada's fridge logger and SD/RTC test sketches as a template;
combining the RTC and SD examples to test the board have got me pretty close to it already;
That all works. Need some data.
One wire example picks up the DS1820 easily enough, need to look at humidity.
This looks promising;
Some notes on it here, (may not be relevant)
This looks like Arduino 1 code, replace #include "WConstants.h" with #include "Arduino.h". That's just something I read here; http://blog.makezine.com/2011/12/01/arduino-1-0-is-out-heres-what-you-need-to-know/
This does something too...
yet another link... sht15 more accurate than HIH4013?
