High Sensitivity Sound Microphone Sensor Detection Module KY-037

Manufacturer

Unbranded

This is a high sensitivity sound detection module. It has two outputs, one for analog output and one for digital output. The analog output is used to measure the sound intensity and the digital output is used to indicate when the sound intensity reaches a certain threshold. The module also has a mounting screw hole and a power indicator light.

100% brand new and high quality For sound detection module has two outputs:
1. AO, analog output, real-time output voltage signal of the microphone
2. DO, when the sound intensity reaches a certain threshold, the output high and
low signal

Module features:
1. there is a mounting screw hole 3mm
2. the use 5v DC power supply
3. with analog output
4. there are threshold level output flip
5. high sensitive microphone and high sensitivity.
6. a power indicator light
7. the comparator output is light Digital Output:
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
{
digitalWrite(Led,LOW)
}
} 2.Analog Output:
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);
