SLC_THRM with micro-SD logging[edit | edit source]

  1. Link to OSF repository for code
  2. Equipment specifications:
    • Logs temperature data from 4 thermocouples once every second
    • Capable of running for 1190 hours with an appropriately sized micro-SD card

Operation & Procedure[edit | edit source]

  • Attach each thermocouple with Kapton tape (or some other high-temperature tape) to their measurement locations
  • Connect power to the Arduino via mini-USB to a 5V wall supply (an iPhone charging block also works)
  • Plug in the micro-SD card
  • Wait until the LED on the Arduino periodically flashes (each flash is a single data point saved to the micro-SD card). The micro-SD card slot might need a wiggle to register at first (there may be a loose connection in the breadboard).

When you're finished logging data:

  • Plug the micro-SD card into a computer with the micro-SD to USB adapter. A file should exist called "TEMPDATA.txt". This is a comma-separated file so it can be easily imported into OpenOffice Calc or Microsoft Excel.

  • If the micro-SD card is unplugged while the Arduino is logging data, press the reset button before plugging it back in.
  • If the LED on the Arduino isn't flashing while running, then the temperature data isn't being stored on the micro-SD card. Try resetting the Arduino with the reset button and try plugging in the micro-SD card again. If it still doesn't flash, there may be a loose connection in the breadboard. Make sure each wire is firmly connected.
  • Make sure to save the data off the micro-SD card to a computer between each test. The Arduino will overwrite existing data on the micro-SD card each time it restarts.

Shutdown[edit | edit source]

Unplug the Arduino to shutdown.
