Nice project. I could use a similar sensor in my own project (alarm with arduino and rpi, with motion detection cam)

I am not clear on the pull up 10K resistor. Can you provide a circuit sketch? The photo is not clear.

I keep getting an error on "Serial.begin(9600);" "serial was not declared in this scope".

Any idea what I need to change?
