Grove Analog microphone outputs

Hi everyone,

I’m new in Arduino world. I’m very surprised by the lack of information on certain sensors like microphones or similar products.

Would you mind clarifying the outputs of the Grove Analog Microphone, please?

The outputs specifications are not described here:

What kind of data in primary output, secondary output? Yellow/white outputs.
Is-it digital outputs or analog?
Audio signal? Sound level? Other?
What unit of measure?
What types of data if any (integer, float etc….)?
What range (for ex 0-1024?) ?
How to interpret the output value range?

I searched the web to find answers but unfortunately I can’t find it.

Hope someone would be able to help me. :slight_smile:

Best regards.
