I've been lurking around these forums for a year or so just gathering information for now, But I would like to get a CNC someday!

I'm currently working on building a regular router table based on the attached picture.

I'm also planning on building a motorized lift for the table using a 24 volt DC gearmotor.

What I'm looking for is some information on setting up a Arduino to stop the gearmotor when the router bit touches a brass plate. I don't know much about the Arduino, But it sounds like it would be possible to use something like a KY-036 sensor module to control some type of relay to stop the gearmotor?
