Overview

The Sound sensor module is a simple microphone based on a opamp LM358 to amplify the sound strength of the environment like door knocks, etc loud enough to be picked up by a microcontroller's Analog to Digital converter. The value of output can be adjusted by the potentiometer.

Applications

  • Simple microphone
  • Sound detection

Connection Diagram

Examples

void setup()
{
 Serial.begin(9600); // open serial port, set the baud rate to 9600 bps
}
void loop()
{
     int val;
     val=analogRead(0);   //connect mic sensor to Analog 0
     Serial.println(val,DEC);//print the sound value to serial       
     delay(100);
}
