Identifying Geekcriet modules from the 37-in-1 bundle

 Why should I care about this?

I recently bought this bundle of sensors from Geekcriet with 37 different sensors intended to be used with an Arduino board. Because this is a cheap chinese product, no instructions or descriptions where provided, and searching the internet I found bit and pieces, but not a complete list to help me out.

The modules

Each of the modules have printed an ID on the PCB, but these seem to be unique to Geekcriet and not some kind of standard, so by finding similar modules from other manufactures where other people have described them, I compared their pictures with my modules and made this list.
Disclaimer: I have for now only cataloged the modules, not been able to try them out to actually verify it.
At a time in the future I might also get round to finding code samples for using the modules and add that to the list or as separate posts.
