Datasheet

Note the cool double-sided y-axis scales! You can zoom in on stuff pretty easily too.

Other plotters

Our friend John also suggests Live-Graph as a free plotting

program (http://adafru.it/c7o) (http://adafru.it/c7o) - we haven't tried it but its worth looking

at if you need to do a lot of plotting!

Portable logging

Of course, having a datalogger thats chained to a desktop computer isn't that handy. We

can make a portable logger with the addition of a battery pack. The cheapest way to get a

good amount of power is to use 6 AA batteries. I made one here with rechargables and a

6xAA battery holder (http://adafru.it/248). It ran the Arduino logging once a second for 18.5

hours. If you use alkalines you could easily get 24 hours or more.
