I've send email today requesting price still waiting for response.

Yes i know but do you think it is hard to connect it and make readings with arduino?

That Sharp sensor would work form me the minimal distance is the problem, i need 0.8 mm and for what i've seen they don't have that kind of sensors.
Do you think that this would work?

Check the ZADM 034
(ParCon, analog output)

Please

I can't use that type of things you just mentioned because the wood is always "runing" on the machine...

yes i can be measured from the side if that is what you are asking.
But your are saying that the capacitive is not going to work for me?

Thanks

You mean something like this

?

A webcam to measure thicknesses??

From Figure 11 the change in current between 0mm and 1mm is quite small.
So that means if i want to detect changes from 0.8mm to 0.85 or 0.9 it will be hard or almost imposible right?
Any other sensor that it's possible for me to use?

Thanks for the quick reply.
The sensor datasheet http://www.vishay.com/docs/83751/cny70.pdf
I need an accuracy like 0.8mm to 0.82 or 0.85 more less.

Thanks

Hello guys
I'm not new with arduino and electronics, but i have a question that i need to ask to people that know a lot more then me.
I want to use a sensor with arduino to measure from 0.8mm to 6 or 8mm. I have a machine that is always working with wood sheets and i need to read the thickness of the sheets with the machine working, do you think it can be done with CNY70 optical sensor?
If not is there another sensor that can do it?

Thanks guys
