Very useful device. Better documentation needed.
For Extreme low power data logging shield for Arduino
The data logger was bought to record battery voltage in a remote Antarctic camp every 15 minutes for 3 months in summer 2015/6. Existing solutions draw significant power, whereas this device draws almost none.
Problems were encountered because the Data Logger does NOT work with UNO r2 - it looks as if it does, but stops after a few recordings. I bought UNO r3 and it worked. Also I inadvertently reversed the shield power leads, which, although there is protection against this, apparently caused the shield to stop indicating SD card recording. It took some time to work this out.
Geir was very patient and helpful in debugging the device, allowing me to get the Data Logger ready in time for deployment to Antarctica.
The device will return in February 2016.
I was impressed with the ability of the datalogger to record for extended periods, and bought a second one.
The documentation was correct, but a bit too short in my opinion. I would have liked a little more explanation of how the logger worked, with better specifications and a description of the software.
