Simple filament runout sensor

how does this work when running from cura? does the software show paused, and do you have control of the printer, just like you paused it in cura?

Also, any idea if this can work on the mini?
I just asked about a similar product in the development area. https://forum.lulzbot.com/viewtopic.php?f=16&t=4947&p=29375#p29375
