I've got a Raspberry Pi that is only a short distance from my tank, and I'm thinking about writing a script that could graph the temperature variations in my tank (As the last few days have been hot, I'd like to see this, maybe even from work). I could leave it running 24/7, and it'd only use a few Watts.
However, I'd need a USB thermometer that is safe to measure the temperature inside the tank. I have a digital one at the moment, but it only outputs to a screen on the outside of the tank.
I'm wondering if anyone here has had any ideas for where I could get one from?
