I used a PIC 16F84-A and spent about two months developing 800 lines of assembly code to assess each event and not trigger on false alarms. I also had about 6 Beta units out in the field to look for problems that had to be addressed. My approach was to be warned while within shall we say ballistic range of my car and trailer to avoid a theft in the first place. A GPS enabled phone could be used with the device I suppose if tracking was desired. I was just trying to make something that could sell for under $50 and not incur a large monthly alarm fee. Although this sounds selfish I really don't want to share the design and software because of all the effort that went into it.
I set one up with its own charger in our vacation house that will alert me since we don't have a phone there, but we do have cell service. The plan would be to call the police if it is triggered there.
