The sensor is USB, 3 axis. They are selling them one-off for $50. I don't know what they would charge for a batch and/or what they would cost for a large production run. It comes with a small compass glued on the top. Their installation directions request that it be oriented correctly and bolted down. Big quakes are ballpark of 1G ground motion so it helps if the sensor doesn't get bounced around. (I wonder how many internet connections would survive a big quake. I don't care if your display gets trashed. Does your router/modem survive?) I think their software will run off the accelerometers built into some laptops. -- These are my opinions. I hate spam.
