1. A sensing device, comprising:
at least one vibration sensor that responds to sensed vibrations;
at least one drive-sense circuit coupled to the vibration sensor, wherein the at least one drive-sense circuit includes:
a first conversion circuit configured to convert a receive signal component of a sensor signal corresponding to the at least one vibration sensor into the sensed signal, wherein the sensed signal indicates a change in an electrical characteristic associated with the at least one vibration sensor; and
a second conversion circuit configured to generate, based on the sensed signal, a drive signal component of the sensor signal corresponding to the at least one vibration sensor, wherein the drive signal component includes a power signal and the receive signal component indicates an effect of the at least one vibration sensor on the power signal.
