DAQduino

DAQ Arduino, Voltage and Current Data Aquisition Unit.

Goal

DAQduino is a standalone DAQ device capable of logging data from a few sources to a CSV file on an SD card, sending data in realtime to a PC, and displaying the data for a particular sensor on a screen

Using Arduino for Data Aquisition

There are several different methods that could be used for basic Data Aquisition tasks with just a few sensors that are easy to integrate with the Arduino Platform.

1. Arduino streams serial data in CSV format.

   • Use Putty/Kitty to record log
   • Python program to log to file
   • LabVIEW program to log to file

2. Arduino streams data in JSON format.

   • Use Putty/Kitty and export data later
   • Python to log to file

3. Arduino waits for serial message to release data packet

   • Putty/Kitty to record log
   • LabVIEW for full DAQ implementation
   • Python for basic IO Interface - command line?
   • Python Desktop App

4. Full Integration between arduino and desktop software.
