How can I measure thickness?

Hello all,

How can I measure the thickness of a sheet made up of any material and apply the same mechanism to measure the thickness of a hollow container

Is there something that would work for any material? but in real life would want to measure thickness of metal and non metal primarily plastic, copper, mud/clay sheets. These 3 primarily.

Is there a way to make it portable? Only software or mobile based?

Don’t know what can I use to measure thickness?

Thanks

Maybe some kind of capacitance sensor.

You would have to calibrate to the material being measured.

Looks like there are lots of hits on Google to start your research from.

Google is you friend! Search for "thickness gauge" and look at the images.

You can easily interface an Arduino to one of the cheap digital calipers:

How well suited calipers are to measuring the thickness of a container would depend on the shape of the container.

Mechanical measurement, such as those digital calipers, is the only way that would work for any solid material.

Other solutions could include ultrasound, capacitive, conductive, or even other methods - those all depend on the material measured whether they work in the first place, and require calibration for each different material.
