Here's a handy Arduino shield: we've had a lot of people looking for a dedicated and well-designed data logging shield. We worked hard to engineer an inexpensive but well-rounded design. Not only is it easy to assemble and customize, it also comes with great documentation and libraries.
New! we now are carrying an 'assembled' version of this shield, with all the components pre-soldered. NOTE: You will only need to solder on either plain 0.1" headers (included) or stacking headers (not include) to attach to your 'duino.
You can get going quickly - saving data to files on any FAT16 or FAT32 formatted SD card, to be read by any plotting, spreadsheet or analysis program. We even have a tutorial on how to use two free software programs to plot your data
The included Real Time Clock timestamps all your data with the current time, so that you know precisely what happened when!
Please note that this item does not come with an Arduino (you'll need one to use with the shield), SD card or coin cell battery! The shield comes with all the components soldered on and tested but does not have headers installed. You'll need some basic soldering skills to put it together, but even if you don't have much experience you can get it done in under 15 minutes.
For more information, including libraries, schematics and examples see the data logger shield webpage . Right now the documentation still refers to the kit version, we'll be updating it shortly to reflect the new assembled shield version.
