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.
-
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
-
Arduino streams data in JSON format.
- Use Putty/Kitty and export data later
- Python to log to file
-
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
-
Full Integration between arduino and desktop software.
Functions:
- 10v, 12v and 24v outputs for sensor power
- 0 - 10v analog input
- 0 - 5v TTL IO
- 4 - 20mA input
- OLED Screen
- Encoder Control
- Basic Scaling
Stretch Goals:
- 0 - 10 v output
- 0 - 20 mA output
Communications:
- Serial Data
- Labveiw Integration?

Questions
How big is the Daqduino PCB?
It measures 68.6 × 53.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Daqduino use?
39 parts, built around the LM358 and TXS0108EPW. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Daqduino KiCad files?
From the ImogenWren/daqduino repository on GitHub, at the commit this page was made from: the board is daqduino-pcb/daqduino.kicad_pcb and its schematic daqduino-pcb/daqduino-shunt-resistor.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Daqduino design in my own project?
Its repository publishes it under the AGPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
