Find suitable SI units to work with a Vibration Sensor

[Robbie64]

We are working on an IOT project in which we are trying to learn about different vibrations of using Wireless Vibration Sensor
According to the manual, the wireless vibration sensor is giving the output while testing on CNC machine device

0.75, 0.71,0.69 whose SI units are in 'g'(which is acceleration due to gravity according to me ) but I am not aware of suitable SI units which will be useful to make it work with CNC machines.

Any suggestions on this will be a great help.

fraction of g is unit system independent. You can put it in a unit system by multiplying by a unit system's value for g, such as 9.8m/s^2.

As for how to make it useful - that is a matter of what you (or the machine) want to use it for.

There is typically no single "Vibration level" since you will always have a spectrum where the level is strongly frequency dependent.
You can of course talk about the maximum vibration level throughout some frequency range (say 0.1-100 Hz) ; and this then typically given in units of m/sqrt(Hz) (meters per square root Hertz); orr alternatively m2/Hz (same thing squared) .
A typical level for a low(ish) vibration system would be of the order of 1e-6 m/sqrt(Hz)

+1 to what Russ said.

The manual also says "Industrial Grade 3-axis Vibration Sensor with RMS, MAX and MIN acceleration in g". Are those the three figures you quoted 0.75, 0.72, 0.69?

I'm curious. Is cybersecurity a priority for your project?

Hello @CWatters
This value is RMS value only I 'll check with above-shared formulae also to get the desired values
