#217: Microphone Voice & Sound Detection Sensor Module (KY-037)


This module is great for Arduino. Use the analog input pin to determine the sound level surrounding the module.

For sound detection module has two outputs:

   There is a mounting screw hole 3mm

   The use 5v DC power supply

   With analog output

   High sensitive microphone and high sensitivity.

   A power indicator light

   The comparator output is light

int Led=13;//define LED interface

   int buttonpin=3 //Define D0 Sensor Interface

   int val;//define numeric variables val

   void setup()


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

   pinMode(buttonpin,INPUT);//Define D0 Sensor as output Interface


   void loop()


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

   if(val==HIGH)//When the light sensor detects a signal is interrupted, LED flashes










Alternative Code:

 int sensorPin = A5; // 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);



   void loop() {

   sensorValue = analogRead(sensorPin);

   digitalWrite(ledPin, HIGH);


   digitalWrite(ledPin, LOW);


   Serial.println(sensorValue, DEC);
