    It measures in terms of analog voltage and you need to convert them to dB using a formula.

    I would like to use this to send audio frequencies to an Arduino Uno board for light up the 3 different group of RGB LED. The single Led is on by one frequencies of sound (low, medium or high).
    how much sensor i need, one for single led or just one

    It can detect the sound strength of the environment, but not the audio frequencies. If you wanna use one to judge the level of sound, yes you can.

    I would like to use this sensor to detect pure tones and to react Arduino depending of each single pure tone sent. So, can it be used in this way?? Any demo code for this one?

    Hi there, it can only be used to detect the sound strength of the environment. About the demo code you can go to Wiki Page to view and refer to.
