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);
}
