I am looking for the following sensor types:
a) Sound sensor
b) Vibration sensor
c) Liquid level sensor (oil)
The use case behind is the following:
There are many engines, which give of a specific sound and vibration.
When over time one or more of this engines is getting faulty, it often happens that it changes its sound and vibration.
So the sensors should capture these values, and send them on an continuing basis to a server.
On the server is a software, which analyzes these values and gives alarm once certain thresholds is reached.
The liquid level sensor is needed for detecting oil levels of certain engines.
The liquid level should in best case be detected without any steps.
I have all the software to transmit the data to the central and also the central software is ready.
All I need is to find the best suitable sensors for this application.
Maybe you have some recommendations for the sensors for the given use case.
Thanks in advance.
