Thanks for that,in which case I've ordered one of these to play with,as long as the sensor board will work buried under car body filler I'll be a happy man.
Thanks for the link but it looks like I'd have to order at least 10,000 of them which would leave me wondering what to do with th 9,998 that would be left over (LOL or something like that!)
I didn't necessarily mean that you should order them from Snaptron... it was just the first example to come up in a Google search. I have a bunch of them I removed from old keypads. If you were in the US (or I were in the UK), I would just drop a few in an envelope and mail them to you!
wouldnt it be easier to just adjust the sensitivity of the laser? i.e. microchip "debounce" plus a timer to only interrupt the signal after laser has been broken for n seconds?

Quite possibly it would but in the winter it could well be permanantly blocked so I'm abandoning any sort of optical sensing methods for now,also I'm running out of research time as this thing needs to be finished ASAP.
