Hello,
Slightly niche thing here, but I’m using the vision sensor right now and cannot seem to find anything documentation wise for it. I’m registering it under a DINT and each different part has a different value, and to my knowledge I will have to work out what shape / colour is what corresponding integer.
If it exists, then that is my bad, but in the case it doesn’t I just thought it would be nice to add!
Kind regards,
FIO2

Hi factoryio2:
Each element has its own number. Try it with the ones you need. For example, the smooth blue piece is 1, the smooth green one is 4, the gray one is 7…
It’s very simple to test manually by placing a strip of tape with a sensor and observing the reading as it passes under it.
Regards

Hi,
Just to complement what was said, and in case you haven’t checked it out yet, you can find the documentation for our vision sensor [here](https://docs.factoryio.com/manual/parts/sensors/#vision-sensor).
I hope this helps!
