Temperature logging: redux

Previously as I was experimenting with logging the temperature using a Raspberry Pi (to monitor the temperatures experienced by fermenting cider), I noted that the Pi was something of a terrible hack, and it should be possible to do more efficiently with some slightly less common hardware.

I decided that improved version would be interesting to build for use at home, since it’s both kind of fun to collect data like that, and actually knowing the temperature in the house is useful at times. The end result of this project is that I can generate graphs like the one below of conditions around the house:

Three graphs of temperature, barometric presure and humidity spanning a week, where each graph has three lines; one each for the lounge, bedroom and entry. Temperature shows a diurnal cycle with mostly constant offsets between lines, presure is equal for each and varies slowly over the entire week, and humidity is broadly similar between the three lines and varies somewhat more randomly.
