Oops. In my previous post I meant mcModule and not mcDongle. Brain fart on my part!

@jeffmartin - I have done some testing myself with my freezer temperatures and also in my fridge. I had no issue receiving data from the modules although after leaving it in the freezer for a day, the standard cr2032 coin cell battery got quite cold and eventually quit reporting. It wasn't the module (they are rated to work from -40C to +85C) but the battery itself. I mentioned previously that looking at a BR2032 would be a better choice as they are designed to work in colder temperatures. You could, as Kristofferis mentioned, look at attaching a probe-type sensor that could live in the freezer and then your power source wouldn't be affected by the temperature. To learn more about the technical specs for the mc-mod110, please check out website for the technical spec sheet

I did a temperature project maybe 1 year ago and the environment was very cold then I used Lithium Thionyl Chloride batteries. In that project I used LS 14250 from the company saft.
It's a 3.6V battery with the size of 1/2 AA and a capacity 1.2Ah and with a operating temperature range -60C to +85C.

In the system documentation for the mcModule 110 then the  input voltage recommendation is +2.1V to +3.6V (+3.0V Typical) So I think this battery would be great for this task.

So maybe a enclosure that's include space for a 1/2 AA and the module would be good here.

And in the freezer i don't see a problem with the "extra" size of the module, do you?

I have now created a thread about monitoring a freezer.
