Basis Data Export

Utility that exports and saves your Basis B1 device's uploaded sensor data. You can learn more about Basis at http://www.mybasis.com/

Instructions

In order to use this script, you must already have a Basis account (and a Basis B1 band).

Usage:

This script can be run several ways. You can (and should probably) first edit the BASIS_USERNAME, BASIS_PASSWORD, and BASIS_EXPORT_FORMAT values under "Settings" in the file basisdataexport.php so you don't have to specify those values every time the script is run. Make sure the data/ folder is writable!

Method 1 - Interactive Mode

1. Open a terminal window and cd to this script's directory
2. Type php basisdataexport.php
3. Follow the prompts (hit ENTER to use default values)
4. Your data will be saved to /data/basis-data-[YYYY-MM-DD].[format]

Method 2 - Via command-line arguments (useful for crons)

Usage php basisdataexport.php -h -u[username] -p[pass] -d[YYYY-MM-DD] -f[json|csv|html]

Options:
  -u  Basis username (if not used, defaults to BASIS_USERNAME)
  -p  Basis password (if not used, defaults to BASIS_PASSWORD)
  -d  Data export date (YYYY-MM-DD) (if not used, defaults to current date)
  -f  Data export format (json|csv|html) (if not used, defaults to json)
  -h  Show this help text

Make sure there are no spaces between any flags and values!

Method 3 - Via web browser

This requires that the scripts are in a location that is executable via a web server.

http://localhost/basis-data-export/basisdataexport.php?u=[basis_username]&p=[basis_password]&d=[YYYY-MM-DD]&f=[format]

Saving Your Data

If the script runs successfully, your data will be saved in the data/ folder. Files are saved in the format basis-data-[YYYY-MM-DD].[format] (i.e., basis-data-2014-04-04.json).

That's it! (for now).

Data Values

Basis currently returns the following data points. They will represent an average (for heart rate) or sum (steps) over the previous 1-minute period:

• Time - time reading was taken
• Heart Rate - beats per minute
• Steps - number of steps taken
• Calories - number of calories burned
• GSR - Galvanic skin response (i.e., sweat/skin conductivity. Learn more about GSR here - http://en.wikipedia.org/wiki/Skin_conductance
• Skin Temperature - skin temperature (degrees F)
• Air Temperature - air temperatute (degrees F)

There are some other aggregate metrics included in the reponse such as min/max/average/standard deviation metrics for each set of data.

Tips

• You can set up a cron to run once per day to automatically grab your previous day's data (assuming you are syncing your device each day)

• If you want to archive data across a date range you can use curl's [ ] syntax to do it easily (thanks to @Edrabbit for the tip!). For example, to get all of May cached in /data:

  curl http://localhost/basis-data-export/basisdataexport.php?date=2013-05-[01-31]
