2. What sort of shock / vibe is the hardware going to experience. Consider heavy bass radios (if your doing that sort of thing), NVH from the suspension, etc. You'll need to accommodate that in the design.
3. Is it remotely possible that the hardware is going to get wet (like window open, etc.)? Again, another design constraint.
4. How much power will need to be provided to keep things operational? Will the electrical system accommodate it?

This is the kind of info I was looking for.
1. It will be in a car and it gets kind of toasty in Texas so that is a concern.
2. I won't have a crazy radio. My plan was to have this in some type of enclosure with it possibly being sealed with potting epoxy or a silicone type product.
3. No, it would be under the dash so it will be away from water areas.
4. I was planning on making this a stand alone unit with a 12v switched input. The sensor only uses 5v and the LED 7 segment board is also run off 5v. I was also going to run a ground output when in reverse to trigger my InfinityBox to turn on the reverse lamps.
