Temperature Logging Device

Thanks Mike, very cool, definitely an option :), most likely the lightest. I sent an e-mail to inquire.

How about something I could read while in the outback? The thermochron requires the info to be downloaded…which isn't necessarily a bad thing, just want to look into all my options.

The Brunton ADC Pro without the necklace is lighter than most multi-function watches. Hard to beat. I like the summary icon display.

Doesn't the ADC Summit also log data such as temperature readings?

There may be third party devices that will read the thermochron data in the field, or there used to be.

This looks interesting.

I couldn’t find the weight. Since it plugs directly into the USB port, I’m guessing 3x the weight of a USB memory stick; maybe 30g.

It’s not your lightest option once you put the Display request in.

Steven,

I agree with Michael regarding the Thermocron ibutton. It weighs 2 grams on my kitchen scale including the fob (more accurate weight is available on their website). Set the parameters for data logging prior to your hike via the USB dongle and export data to a text file for post hike analysis. I keep the text file in the folder with photos from each hike for reference. It is easy to use the time stamp on the photo to correlate with the time stamp for each temperature reading.

As Mike said: Thermocron.
Also Hydrochron, for combined temp and RH. You can plot out the temperature and Rh with Excel.

Great info, thanks guys. I can deal with 2 grams :)

Steve K, where did you get your setup from? How about price?

It looks much simpler then the one I inquired about.

Steven,

I used the Dallas Maxim site (http://www.maxim-ic.com/products/ibutton/ibuttons/thermochron.cfm).

Hi all,

Another option is the MicroLogLite USB Temperature Data Logger from Fourier Systems (it’s 55g). It’s on sale right now at dataloggerstore.com.

I’ve bought 1-wire equipment (related to iButton) direct from Dallas Maxim in the past, but delivery can be very slow on some items. A good source for iButton items is Embedded Data Systems.

Cheers
