Hi it's my first post so forgive me if straight away I'm looking for help.
I'm attempting to design and build a small circuit that will detect vibrations in the ground. Ideally it would be able to screen out animals and activity on top of the surface. and only detect if the the ground itself is disturbed eg by digging. I had intially intended to use an accelerometer, but I really need it to be able to screen out just general movement. Also I'd ideally like it to have as long a range as possible.
I intend to output to an analague to digital converter, and then to a PC so if neccessary I imagine the PC can do some of the screening. I'm hoping to keep the costs well below $100.
I'm starting to suspect this project is at the edge of my ability but I would appreciate any and all help.
