Hello Kind people!
I want to detect intensity of vibrations in my washing machine and refrigerator at home while it running. I would like to detect abnormal vibrations in many other similar home appliances. Any suggestions on which sensors to use which help detect vibrations at high frequencies and the amplitude of those vibrations?
I read through the previous posts but could not find any sensor which measure amplitudes at high frequencies.

Re: Vibration sensor with amplitude
Accelerometers are commonly used to detect vibrations and measure the amplitude of those vibrations. They work by measuring the acceleration experienced by the sensor and can detect vibrations over a wide frequency range, including high frequencies. The type of accelerometer you need will depend on the specific requirements of your application. For example, if you need to measure vibrations over a wide frequency range, a MEMS (microelectromechanical systems) accelerometer would be a good choice.

Re: Vibration sensor with amplitude
The LID3DH is a good option for that application with data rates up to 5KHz. Vibrations in equipment such as washers and refrigerators tend to be centered around AC line frequency and the rotating speed of moving parts. 5KHz should be fast enough to capture that and any significant harmonics.
