Which sensor should i use for measuring thickness of DOUGH

Using Arduino Sensors

Greetings, I am trying to resolve an industrial issue and currently stucked because i am unable to figure out the possible way of solving that issue.
Actually the project is about a bakery where the thickness of dough needs to be measured.
and whenever it reaches 3mm we need to stop the roller.
I am attaching link of the video for better understanding :

Can you please suggest me which sensor will be appropriate and what are the possible ways to solve this problem.

Thnakyou

you could use a distance sensor (ToF laser) placed above the the dough. You know what's the measure when there is no dough and when there is dough, the distance will be smaller. The challenge will be to find a precise enough sensor to give you an accurate mm reading.

another option would be an articulated roll that sits on top of the dough and the axe would be connected to a precise rotation encoder. you measure the angle and can deduce the thickness of the dough

the Pololu VL6180X Time-of-Flight Distance sensor is accurate to 1mm over a distance of 20cm
interface is I2C so easy to program usinf existing libraries

Hi,
@J-M-L :+1: :+1: :+1:
The TOF would be ideal in a food handling environment, touchless and place the sensor in an easily cleanable and water proof enclosure.

@J-M-L @TomGeorge Thankyou :innocent:
Lets proceed further with TOF first and try it out.

What is wrong with measuring the height of the adjustable roller? Does that not control the thickness of the dough?
