These things could track mice footsteps. That might be hyperbole, I haven't actually tracked mice with them. But I wouldn't be at all surprised if you could!

This uses one channel of a dual comparator IC so not very sensitive. I replaced mine with a dual opamp but still sensor isn't super good either more high frequency than low. But not bad for price.

Output does not reflect the amount of vibration, just whether it has exceeded some threshold, which should be adjustable via potentiometer, but that has little if any effect on sensitivity.

The output is digital. I bought this because it said it was an analog output.

Bottom line, if the system you are designing will have any vibration that is not intended to be detected, these are not the right components for you. On the other hand, the high sensitivity may be a plus if that's what you're intending to use it for. I tested these using a pin in a breadboard as a start and the vibration sensor as a stop, and 8/10 times I could not even unplug the pin from the breadboard without triggering this sensor, even after adjusting the screw head. If you need something with high sensitivity and no tolerance, this is definitely for you. Otherwise, look somewhere else.

Arrived in good time, well packaged and works well, adjustable sensitivity is nice and detects even the slightest vibration.Been used in a Fall Prevention System.
