From comments here on the forum and elsewhere, I get the impression that a lot of people might be interested in building simple data logging systems to record environmental data and that maybe those people don’t know how to get started. In particular, I’ve seen mention of not being able to get data out of fancy logging systems. Building your own stuff and logging to CSV files might be a solution to that.
Here are some links to data logging related tutorials and guides from Sparkfun, the Raspberry Pi Foundation, and Adafruit:
If there’s anybody out there reading this who wants to make a data logging system for your garden, is this interesting? If so, what are your goals? What would you like to measure? How do you plan to use that data? What sensors do you care about? Do the links above help?
