Yes, you can. Also, IR item presence detectors in the paper handling
equipment I sometimes work with. A small digital camera can be a very
handy diagnostic instrument at times. Of course one could build
something much simpler and smaller using not very many components which
would serve as well or better. Actually probably quite a lot better as
the sensor could be much smaller and able to be gotten into tight spots.
I've thought of doing that several times but just never got around tuit.

Yes, Most semiconductior sensors, such as CCDs, respond to near-IR. I am
told you can 'see' most remote cotnrol outputs using one, for examplke.

One should be able to check things by using a digital camera to view with.
Quite likely. The problem is that it was _me_ who was setting up this CX
laser scanner module, and I am sure you know by now the sort of cameras I
have :-)
