## Periodic logging

The logging scripts for I2C sensors normally take only one sample and cron can be used for periodic logging. We normally make a `~/shell.nix` file and a logging script that will open the Nix shell and run the correct tool with the desired arguments. Then we use `crontab` to run this script periodically. Because cron runs non-login shells, we need to add additional configuration to make the `nix-shell` command available. See the snippets below.
