Finometer Data Logger

This project is intended to use an Arduino as a data logger for a Finometer Medical System. The project consists of two parts: finometer_logger.ino and logger.py.

finometer_logger.ino

finometer_logger.ino is a C++ script designed to be loaded on to an Arduino board to interact with the analogue (BNC) outputs of the Finometer. The pins should be set up as follows:

• Finometer Analogue Output 1 -> Arduino Pin A1 (Finger cuff pressure)
• Finometer Analogue Output 2 -> Arduino Pin A2 (Hydrostatic finger height)
• Finometer Analogue Output 3 -> Arduino Pin A3 (Arm cuff pressure)
• Finometer Analogue Output 4 -> Arduino Pin A4 (Finger plethysmogram)

These output values are sent via a serial connection along with the elapsed time since the Arduino started.

logger.py

The logger.py script is a simple python script that logs the values read from a serial port to an output csv file. If no name is provided the output file is named output- followed by the current date an time.
