Helo!
I have arduino duemilanove,and a temprature sensor which works fine even with pachube.Now im just wondering if there is an easy to log sensor data directly on the computer. was thinking maybe to a text file which i can export to excel or other graphing tools.
thanks
I want to log temperatures unattended. It’s in my yard on a periodic basis, so it doesn’t need to be waterproof or anything, but I don’t have a laptop (and the location isn’t close to a window in the computer room) so I can’t log right to the computer.
Temperature loggers seem to be pretty expensive and are single-purpose. Then I thought of the Arduino. For just $35 I can get a general purpose, reusable microcontroller, stick a thermistor on there and I’m done.

Sure, just print the data out the serial port. Use something like a comma delimited format.
On the PC side, write a little program that listens to a serial port. You can use any tool, I prefer Tcl as serial is simple. Or use TeraTerm and log straight from there.
