I believe someone mfgers a device that can be placed along a driveway, and
when a vehicle passes by it sends a wireless signal to an alarm in a home to
signal the event. Whoa! As I was typing this, it occurred to me that I might
have bookmakred such a site once. Here it is <http://www.drivewayalarm.com/>
Are there others? The price of the 1000' alarm is a bit much, $179.

Lowes carry motion detector lights with battery-operated sensors with RF
transmitters ... the range is 100 feet. They cost a lot less than $179 and
might serve the purpose. It should be easy to power a sound device from the
light socket unit, which could be mounted in your home.

Try burying a multi turn coil, a metre or two in diameter, in the driveway.
Connect the two ends to the inputs of an op-amp and fiddle with it until you
get enough of an output signal to do something with.
