Can anyone point me in.the right direction please. I have a device outputting uart/serial data. This is a remote battery powered device. This data l need time stamping and storing onto an SD card. I can then upload the SD card to computer for further evaluating.
I see you can get a RTC module for the Arduino.
Would l need this and a DAQ type of data logger ?
People sometimes print the value of millis() to the SD card, along with each data record.
The Arduino crystal is not a very accurate timekeeper but it can be calibrated. Depends on your requirements.
The Sparkfun OpenLog is a very convenient, inexpensive and stand-alone data logger for serial data. It is possible to edit the open source code so that it adds the above-mentioned time stamp to the data.

I have no affiliation with EstarDyne. They are made by all different manufacturers.
