Data Logger

An Arduino sketch with accompanying Python scripts written for high frequency (kHz) data logging.

Details for sensors and wiring are in Arduino sketch.

Prerequisite Libraries

Arduino

• SdFat

Python

• PySerial
• numpy
• matplotlib (used in data_plot.py demo)

User Instructions

Upload data_acquisition_sketch.ino to Arduino using Arduino IDE.

Run python monitor.py to start serial monitor gui.

Use [Connect] to connect to Arduino, [Refresh] to refresh dropdown of connected devices.

Use [Start] and [Stop] to begin and end sensor data recording to SD.

Use [Read] to transfer binary data from SD (slow), or manually move the SD card and transfer files (irritating).

Use [Test] to output realtime sensor readings to gui console, useful for ensuring sensors are working as expected.

Use functions in data_util.py to convert binary data to other forms (csv file, numpy ndarray).

Run python data_plot.py to display data from binary or csv file using matplotlib.
