I am soon deploying my “arduino” (it’s a waspmote, but fundamentally is an arduino) project and I have the concern that some things may be affected in the winter, when here in Denmark goes below 0. Not so often and not for prolonged period of times, but we do reach -24 C sometimes. Generally I’d say most places -5 to -15. But not constantly.
I read a little about this in the forum (suggestion like using multiple resistors, in series/parallel to spread the heat around the edges of the enclosure) but I was wondering if you guys think this is necessary for this temperatures? I am using a IP67 enclosure and I was wondering if you more expert people could help me to compile a list of TO-DOs to optimize the deployment of arduino in my situation because I am certain i would help other too.
Another point was how and what to use to insulate the arduino to maintain heat and prevent condensation.
I’m excited to hear what you guys suggest.
PS: Not sure whether this is relevant but some of my waspmotes/arduino will be in deepsleep mode for MOST of the time (sending data to my server via GPRS module once a day) and others will be doing almost the same but measuring every 15-30 minutes, sending data only once a day, plus whenever some alarm of what I am monitoring is triggered. Just to give you some context here.
