Data Logger shield for Arduino, Logging

(10 reviews) Write a Review


Data Logging shield for Arduino perfect for Arduino projects!

This Arduino shield has been designed for Data Logging to an SD card and also has an onboard Real-Time Clock, so you can easily time stamp your readings, you can also use the Adafruit libraries which work great with these!
This board is fully assembled with stackable header pins.
Just add your own SD card to log the data to, and write the sketch to take readings and log data. The data can be read by your computer (With an SD slot or SD card reader).
This shield does NOT come with an Arduino, though it does require one to work. The battery is not included due to shipping regulations, so you will need a 3v CR1220 or equivalent

  • SD card interface works with FAT16 or FAT32 formatted cards. 3.3v level shifter circuitry prevents damage to your SD card
  • Real-time clock (RTC) keeps the time going even when the Arduino is unplugged. The battery backup lasts for years
  • Generous prototyping area to add sensors or other circuitry
  • 3.3V regulator to supply your SD card with all the power it needs
  • Works with Arduino UNO, Duemilanove, Diecimila, Leonardo or ADK/Mega R3 or higher. ADK/Mega R2 or lower are not supported.
  • Dimensions (assembled): 70mm x 53mm x 17mm (2.7in x 2in x 0.65in)
  • SD Card protrudes by 10mm (0.4in) when inserted
  • Weight: 22g/0.8oz
  • The real-time clock uses I2C 7-bit address 0x68.

Using the Data Logging Shield:

  • To communicate with the onboard RTC, it's easiest to use Adafruit's RTCLib library. To install the library, open up the library manager within the Arduino IDE

Arduino Library Manager
Then search for RTCLib. Select the Adafruit one and click install:

RTCLIB Install

  • The SD Card - you can access this using the SD Datalogger example built into Arduino, or use the SDFat Library fork from Adafruit:

    I'm total novice to Ardruino and this device seemed ideal for a project. Just been playing with it so far but seems a useful bit of kit and well made. Great service from Proto-Pic and wouldn't hesitate to use them again.

    I had this up and running and definitively installed in a couple of days logging central heating temperatures. All sort of useful sketches to be found, several with useful RTC related stuff (set to PC time, for example). (The RTC makes price very reasonable). Seems happy with up to a 32 Gb card, maybe more. Using Excel to then deal with the .CSV files. Only down side is it is the older version, but no real issue at all, just commits you to specific pins.

    Early days yet but so far does the job.The Ada site has a good walkthrough to be read carefully. I had a tussle getting Open Office to make graphs but minor tweaks to the sketch resolved that.

    Works very well, very impressed. Using this for taking temperature readings from a remote weather panel

    I have made progress with using this shield since my earlier review. For some reason I had missed the logging example on the Adafruit site, and also the shield schematic is on the site under 'downloads' and with this information I have been able to use it

    This shield is a great way to get data storage and a real time clock as well. Read the information on the Adafruit website, not much to assemble but worth it.

    Very useful shield, very simple to get started logging adaruit tutorials are very useful, and quite easy to get more advanced (faster logging) RTC is straightforward to use for logging time or time stamping files, an invaluable bit of kit for learning

    Just received an Arduino data logging shield and now working on a simple weather station.Perhaps a note about the advantages or disadvantages of using male to male connector pins as against stacking connectors could be useful when using a pro type shield

    The RealTime chip is great in combination with the data logger. It does take a lot of arduino flash memory though.Excellent shield, although I am not a fan of the prototyping area.
