Hello there. I am looking for other people who are familiar with putting the Raspberry Pi in extreme temperature conditions. Just curious for experiences/stories/tips/whatnot.
I have a small army of Raspberry Pi Zero's here. And last winter I kinda put them through the test with having some of them outside. They were put in a small box, controlling a relay. Although we did not had a super cold winter, it got down to -35°C for a while. Only one Raspberry failed, except it wasn't the RPi as it turned out. The tiny gpio wire going to the relay couldn't carry the 3.3V over to the relay. The wire was completely solid. Moving it over to the 5V pin fixed it. The RPi itself did great had no issues. I learned that I need to get thicker wires to compensate for the increase in resistance, and keeping them as short as possible.
Interesting the internal cpu temperature (when I was monitoring it) did not get much lower than -15°C. Possible because it was doing work, as well as being right next to the power supply.
I am planning for a 12v battery powered, mobile connected remote camera this winter. Undecided if I have it heated or not. Right now the camera is my biggest question as I don't know how well it performs in cold environments. I'm hoping it will perform all the way down to -40°C which is usually the lowest we get around here.
Right now we have some pretty hot temperatures. One of the Pi's is continuously streaming its webcam feed and is in direct sunlight most of the day. Only now I realised that the internal temperature has risen to 90°C and has been like that for the past few days probably. I find it odd that the cpu has been throttled to 1.0GHz, but 'vcgencmd get_throttled' still shows 0x0. The despite the load being 5.30 it hasn't skipped a beat with streaming. I know coldness shouldn't permanently damage electronics, but does anyone have experience with hot temperatures?
