Since they say it can be adjusted for any range of forces I wonder if it could be used as a gravity sensor. Or as a seismometer to detect earth movements, nearby vehicles, even people walking. With a few of them it would be possible to locate all the things causing vibration in a large area. The US Army fields arrays of sensors to do things like this: https://en.wikipedia.org/wiki/Unattended_ground_sensor https://en.wikipedia.org/wiki/Unattended_ground_sensor They can even tell what is causing the vibration from the pattern of it. Very hard to hide any movement from a system like this. I wonder if these are being used in Ukraine.
