Step 5 Close the field of view for the PIR

So the PIR has a crazy wide field of view, I closed that down by using a 5" piece of poster tube, I got this idea from a post on the parallax forums, they used a wider tube, but it was still a really slick Idea.

I secured the PIR to the tube by putting a hole in the cap of the tube and hot glueing it.

I connected this pack to the breadboard by using phone cord, I had tons of it laying around. I found a 3 prong connector on an old CPU fan that I used as a plug for the PIR.
