Unfortunately there is not much documentation.  Would this interact with
something in the host (e.g. emulating the sensors)?  Or is it like USB
where QEMU has emulation of both controllers and devices (e.g. tablets
or storage)?

There are lots of different devices in QEMU; a student with good code
reading abilities should be able to find what he needs, but if you are
writing an entire emulation subsystem it's going to be a lot of work.

I don't know if someone is available to mentor the project, but the
mailing list would surely be of help.
