For a little project of mine i want to monitor the fill level of a tank. As though by chance i knew someone who had two of those IFM KQ6001 capacitive sensors laying around.
I have a hard time understanding what exactly they are doing when they detect the fluid/"switch". There are three cables on the sensor as can be seen on that little graphic here:
Do i understand that right that the brown and the blue wire are used for energy supply (e.g. 12V) and the black one is the IO-Link.
Whereas i understand IO-Link meaning some kind of data output?
My question is now, how do i manage to read the KQ6001 sensor with a raspberry pi?
In advance thanks a lot for your help and sorry for my lack of knowledge!
