Here's the plan. I want to measure the temperature in beehives in 2-3 different places. There's no mains power. A UK beehive is 46x46cm. my assumptions are: I can buy temperature guages that are accurate enough that output data I could try and figure out writing device drivers for them into unix a Raspberry Pi could do all the smarts and write out to a USB drive solar panels on the beehive roof could power it. There are very specific circumstance when I'd want data logged every 5 minutes or so, otherwise every hour or more would be fine. Aside from powering the thing it doesn't seem that hard to do apart from me figuring out how to write software at a level I've never had to consider before but can solar in this precipitous shithole work to power something like a Pi?
