Thermochrons are fun!

I received my DS1921L in the mail on Friday (I ordered it at the beginning of the summer, but oh well).

In a nutshell, this is a device the size of five dimes stacked on top of each other. It has an onboard clock and temperature sensor and enough memory to store up to 2048 temperature samples, with a sampling interval of between 1 and 255 minutes. (I can’t believe something so small can do this :-)

We’ve been having trouble with our vegtables freezing, so I stuck the ibutton in there for a day with one-minute sampling and got an interesting graph. It’s not our imagination, something really is wrong with our fridge.

The manufacturer has basic temperature sensors in both iButton and standard packages. The standard ones are great for putting computer monitored temperature sensors all over the place…
