High Sensitivity Microphone Sound Detection Module KY-037

• Size: 32mm * 17mm * 8mm (length * width * height)
• Main system: LM393, electret condenser microphone
• Operating voltage: DC 4-6 V
• Signal output indication
• 
  

Features:
- 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
Arduino Example code:
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
 {digitalWrite(Led,HIGH)}
 else
{digital Write(Led,LOW)}}
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);Serial.begin(9600);}
 void loop() 
{sensorValue = analogRead(sensorPin);
   digitalWrite(ledPin, HIGH);
   delay(sensorValue);
   digitalWrite(ledPin, LOW);
   delay(sensorValue);
   Serial.println(sensorValue, DEC); }
