New Toy

I have a new toy, a birthday gift from my parents.  It’s a temperature/humidity datalogger (this one— one of the few compatible with Macs).  Basically, this gizmo keeps a constant internal log of the temperature and humidity, at intervals you specify (every second, every hour, whatever you like).  Then when you want the data, you plug it into your computer’s USB and all the stored information downloads.  The software makes lovely graphs, and you can export the data to Excel for further manipulation.  It’s very cool.  If you find such things cool.  I stuck it on the underside of the kitchen island.

Now, here is the first readout, comprising three nights and two days (most of which we were at home).

The nights, as you can see, produce lovely “decay” curves as the house gradually cools (the first night it was about 30º out, the past two have been warmer.)  The steepest upswing, on Day 1, was a brief fire– you can even see a blip where it started to die, and J. added a second log.  The more curved upswing on Day 2 represents a bit of space-heater use.  All the other small upticks are making coffee, french toast, grilled cheese…  Overall, our temperature over this span averaged 59ºF.

    I couldn’t find it in the specs, but how many days of data can it store?

    I did, however, find the question “I cannot communicate with my HOBO Shuttle!” You gotta love a device that has a HOBO Shuttle.

      Depends how frequently you wish it to sample. I believe it can store something like 56,000 data points. So if you sample every 10 minutes, it should be able to store over a year of data.

      Personally, I hate it when I can’t communicate with my HOBO shuttle…

    That’s the Yeti hat! It’s super-warm, and highly fashionable. You should ask O’G to buy you one for Christmas!

    OMG, I love this! Being a total data geek, I would totally love one of those.

    If my blog weren’t hosted by Blogger, I’d be tempted to get one of these and have the data uploaded to my blog for real-time data. But, I’m getting ahead of myself there…

      CC, you seem to have great success at getting people to send you products to test out– give Onset a call and see if they’ll give you one (or two, so you can give the other away to the “winner” of the FYB Challenge!)
