Perhaps
find "$1" -type d -printf '[ -f %p/SENTINEL-1 -a -f %p/SENTINEL-2 ] && echo %p\n' | sh
You would need to do minimal rewriting for the other uses you mention. But
it won't work if the file names may contain characters which are special
to the shell.

I would need to see an example to be clear what this means.
