    KY-038 Small sound sensor acts like a microphone which detects sound signals. The sensor will detect sound signals and provide digital or analog output. The sound sensor can be used to make exciting projects like clap switch or any project based on sound detection. It’s very cheap

    and  has 3 main components on its circuit board. First, the sensor on the front side of the module which measures the area physically and sends an analog signal to the amplifier. The amplifier amplifies the signal, according to the resistant value of the potentiometer, and sends the signal to the analog output of the module.
    The third component is a comparator which switches the digital out and the LED if the signal falls under a specific value. 
    You can control the sensitivity by adjusting the potentiometer.


    Power supply voltage: +5V

    Power On LED light: LED1

    Electret Condenser Microphone (ECM) sensor

    AO = analog output provides a real-time output voltage signal of the microphone

    DO = Digital output, output goes high when the intensity of the sound reaches threshold

    Comparator Circuit: LM393

    Comparator Output LED: LED2, on when sound reaches threshold

    Built in potentiometer can be used to adjust the DO threshold level

    Mounting screw hole size: 3mm

    Circuit Board Dimensions: 35mm x 15mm x 14mm (L x W x H, excluding connector and microphone)

    Operation:


    Pin + to +5VDC

    Pin - to Ground

    Pin AO to Microcontroller Analog Input (for analog program)

    Pin DO to Microcontroller Digital Input (for digital program)

    LED1 will illuminate when power is applied

    Turn potentiometer counter-clockwise until LED2 turns off. This is the sound threshold. Then adjust to the appropriate threshold for your application.

    NOTE: The electret microphone in this module is not extremely sensitive. It is designed to detect loud noises (door slams, glass breakage, dogs barking, doorbells, alarms, buzzers, etc.).

    Sketch/Source Code :

    int soundSensor=2;
    int LED=4;
    boolean LEDStatus=false;
    
    void setup() {
     pinMode(soundSensor,INPUT);
     pinMode(LED,OUTPUT);
    
    }
    
    void loop() {
    
      int SensorData=digitalRead(soundSensor); 
      if(SensorData==1){
    
        if(LEDStatus==false){
            LEDStatus=true;
            digitalWrite(LED,HIGH);
        }
        else{
            LEDStatus=false;
            digitalWrite(LED,LOW);
        }
      }
     }
