The Arduino transmits the measured temperature of each point via the usb serial port to the JAVA programm, where they are all saved and processed.
It would also be possible to save them on a SD Card to make the device independent from the PC while measuring (plus adding a lipo or so for energy supply), but that makes the whole project more expensive.
Heh, what I ment, is it serial data, analog or something else?
I formatted my question badly.
Cheers,
