KY-037 High Sensitivity Microphone Module Sound Sensor

KY-037 High Sensitivity Microphone Module Sound Sensor

Package Dimensions 3.74 x 2.64 x 0.47

Module has two outputs:

AO, analog output, real-time output voltage signal of the microphone

DO, when the sound intensity reaches a certain threshold, the output high and low signal [threshold - sensitivity can be adjusted via potentiometer]



Module features:

3mm mounting screw holes

Use 5v DC power supply

int Led = 13 ;// define LED Interface

int buttonpin = 3; // define D0 Sensor Interface

int val = 0;// define numeric variables val



void setup ()

{

pinMode (Led, OUTPUT) ;// define LED as output interface

pinMode (buttonpin, INPUT) ;// output interface D0 is defined sensor

}



void loop ()

{

val = digitalRead(buttonpin);// digital interface will be assigned a value of pin 3 to read val

if (val == HIGH) // When the sound detection module detects a signal, LED flashes

{

digitalWrite (Led, HIGH);

}

else

{

digitalWrite (Led, LOW);

}

}

Example Code : analog outputs

int sensorPin = A0; // select the input pin for the potentiometer

int ledPin = 13; // select the pin for the LED

int sensorValue = 0; // variable to store the value coming from the sensor



void setup ()

{

pinMode (ledPin, OUTPUT);

Serial.begin (9600);

}



void loop ()

{

sensorValue = analogRead (sensorPin);

digitalWrite (ledPin, HIGH);

delay (sensorValue);

digitalWrite (ledPin, LOW);

delay (sensorValue);

Serial.println (sensorValue, DEC);

}
