Accrochages

The microphone sensor detect noise activity (5 meters). We can change the amplitude buffer by changing the capacitor value. The mic react by the airwave modulation.

• The sensor could recognize a hand clap ( high amplitude, short time wave)
• The repetitive sound like persone walking hard.

We can add filter (capacitor and resistance(not on photo))to reach specific frequency sound

• Bass sound from truck passing or ghettoblaster !!
• High sound like whisle, child laughing
