Here is a handy Arduino shield: Many of us have been looking for a custom and well-designed data logging shield. We have worked hard to design an affordable yet versatile solution.
The latest version of this popular shield has all the features of the original and is "R3" compatible, so you can use it with almost any Arduino or compatible board. You can get it up and running in less than 15 minutes – it can save data to files on any FAT16 or FAT32 formatted SD card to be read by any drawing, spreadsheet, or data analysis program. The included Real-Time Clock (RTC) can be used to timestamp all your data with the current time, so you know exactly when events occurred!
Please note that this item does not come with an Arduino (you'll need one to use it with the shield), an SD card, or a button cell battery. The shield comes with all the components soldered and tested but does not have headers attached. You'll need some basic soldering skills to assemble it, but even with limited experience, you can put it together in less than 15 minutes.
Of course, you can record anything you want, including digital sensors with Arduino libraries, serial data, bit timing, and more.
You can order the Adafruit Assembled Data Logging Shield for Arduino from the Adafruit category at SAMM Market with competitive prices, same-day shipping, and fast delivery.
