Re: Bar code OEM modules

My main concern going this route is the sensor. I presume one would need
some optics and suitably positioned emitter and sensor to get reliable
results. Are there chips/modules out there that would include both the
electronics and the optics? Googling for barcode sensors is a tad
frustrating, as the results just show loads of complete barcode scanners.

While poking around looking for suitable components, I stumbled
upon this page:

I am not suggesting you follow their approach but it gives you a
crude idea of what's involved. In particular, their home-made
emitter-detector resembles the sorts of commercial reflective
emitter-detector pairs available (though the commercial devices
are made without *wood*! :> )
