Well, I'd even yield the point on data logging, but the information of how to actually do that is, shall we say, sparse! There is no information on the data format, but a mention of an optional USB cable. When you go to their site, and I'll be dipped if I can find any more information about the mystery USB cable or the data format from this device. Given that data logging seems to be elusive, to say the least, I'd pick something more capable and small
A unit like this is WAY more flexible and capable. If you're willing to go overseas, similar items start around $10.
