Installation

1. Clone the repository:

   git clone https://github.com/ryanfitzsimon/sensorlog

2. Connect the sensors to the Raspberry Pi GPIO headers.

OPC Pin	Function	RPi Pin
1	5 V	4
2	CLK	23
3	MISO	21
4	MOSI	19
5	CE0	24
6	GND	25

3. Ensure that the required devices are enabled in the device tree. The following line should be present in /boot/config.txt

   dtparam=spi=on
   

4. Run the install script:

   cd sensorlog
   ./install.sh

   This will install the required python modules, add udev rules to allow access to the required devices and create a symlink to sensorlog in /usr/local/bin.

Running Sensorlog

usage: sensorlog.py [-h] [-l logfile] [-t period] [-v]

Select the logfile location using -l. The default is opc-log.csv.

The period in seconds can be set using -t.

Verbose mode can be enabled with the -v flag. In verbose mode, each line written to the logfile will also be printed to stdout.

Uninstallation

Simply run the provided uninstall.sh script.

./uninstall.sh

Note that this only undoes the actions performed by the install.sh script. It will not remove any python modules or modify device tree settings.
