Could someone point me in the right direction to view the wiring and
schematic diagrams of the FM or AM seismic sensors? I am curious to see how
they operate. Keep in mind the following: Automatic traffic signals are
using similar concepts to detect presence when a car waits at an
intersection. Notice the wires lines on the pavement, they lead to a box at
the intersection which times the traffic signals.
