If you type "sensor" in the search bar of this Forum and click the "titles only" button all the information you need is available. The Spark manual is online from the DJI home page with additional info including diagrams and specs.

When your research is complete you can post the results here and we can perhaps help you find the ones you've missed. Sounds like a fun project. Good luck!
