Hi,
how can I interpret the values between 0 and 1023 that I get from reading these sensors with Arduino?
I have not found bands of values or indicators a bit 'more specific about which indicates a certain range of values.
If anyone has any ideas to help me thank you very much! 
PS: I mean something more specific than just a percentage value
The best way to look at this as taking the analog world and cutting into 1024 slices to see where they lie. But they are not exact and can wiggle a bit depending on the ADC circuit. Example:
I have a resistor (pot type) that varies from 500 ohms to say 21K ohms and apply say 5V. Imagine it had 1024 clicks. Each click would be (21K- 500) / 1024 ~= 20 ohms.
Now 5 volts are held back by the resistance of 20 ohms. But this is not linear unfortunately. So I stop here and let you build this and try for yourself. Most people will build and then calibrate the design to fit the needs by trial and error. (All math and laws deleted for simplicity
)
Hope this clears the air,
Clem
