Here is a picture of the data logger, almost complete. This is based on an Arduino board and SD card shield. The software onboard is able to read the voltage input and write out a CSV file to the SD card, for analysis in Excel. There is some work still necessary to scale the voltage range to 12V, and then I plan to package this up into a box to protect it from the elements.
