Fine!
What would it take to build a sensor based on this physics

?
One IR-LED and maybe 4 photo diodes, or a prism combined with a linear CCD?
Some slow ADCs in a cheap MCU.
It seems possible to do this
I am certainly no expert in this area, but the specs call it NDIR and
there is a wikipedia page on that topic:
