Title: Water temperatures
Post by: AndrewPratt on December 14, 2017, 12:34:13 pm
Thanks to Josh's help we've now deployed our Demo 205 with the thermistor outside our office here to see how well it stands up to winter temperatures. I've installed lithium batteries but am curious what other people's experience has been with these when left outside?

@Andrew - This is awesome! Great Job!

To address your question - we have done some testing with the mcDemo205 outside in the middle of winter as well - Using Lithium is the best choice as they are rated for much more extreme temperatures (versus Alkaline) and have a higher capacity. Using Lithium should perform very well outside!

As a follow up update we have now had the 205 outside during this bitterly cold stretch over Christmas and it has continued to push out hourly updates without issue. Yesterday we hit -33C and it still worked fine. One thing I have seen consistently though is that with the clear front on the 205 unit it acts like a greenhouse when the sun shines directly on it so despite it been very cold I see a rise in day time temps around 1pm to well above zero for an hour or so before it plummets back to ambient temp. When I'm back in the office next week I will see about adding some sort of shade device to minimize that effect.
