High Sensitivity Microphone Electret Condenser Sound Sensor

350033

New product

KWD 0.750

A microphone module featuring a high-sensitivity large-format electret
capsule. Output ‘DO’ (active high) is switched when the sound level
exceeds a preset level. A pot allows adjustment of the level. The analog
output signal is available at the ‘AO’ pin.

product description

Operating Voltage3-15V DC
Board Size3.2 cm x 1.6 cm

A microphone module featuring a high-sensitivity large-format electret
capsule. Output ‘DO’ (active high) is switched when the sound level
exceeds a preset level. A pot allows adjustment of the level. The analog
output signal is available at the ‘AO’ pin.

Microphone sound detection module

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

The threshold-sensitivity can be adjusted via potentiometer on the sensor

Connecting to the Arduino

  • Pin + to Arduino 5+
  • Pin - to Arduino -
  • Pin A0 to Arduino A0 (for analog program)
  • Pin D0 to Arduino 13 (for digital program)

Example code: Digital output

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);
}
