I was leaning towards a 12F675, which has A2D and is nW

As far as the overall project goes, I'm trying to put myself in their
shoes. This is part of their general coursework and the business is
not intended to last for the rest of the year.

Their main goal is to demonstrate good business practice, which
includes not losing a heap of money (better still, make a healthy
profit) by successfully marketing a product

My main goal is to help them meet their goal by designing and building,
in record time ! , a short run of reliable, effective alarms with a good
mark-up margin. Originally they suggested a run of 200, but without
any market research I thought that more than a little risky

So I'm all for simplicity, and an accelerometer + PIC certainly is
that, now I need to work on the price
