Analog Sound Sensor module ,

 29.0

Product ID: 2486 SKU: sens-2486 Categories: , Tags: ,

Sensitive Microphone Sensor Module with Analog and Digital/Comparator Outputs. Can be used with Arduino Uno/Due/Mega/Leonardo and with other microcontrollers and embedded boards.

Pinouts

  1. AO : analog output, real-time output voltage signal of the microphone
  2. G : Power Ground
  3. + : Positive VCC (3V-5.5V Nominal : 3.0V – 5.0V)
  4. DO : Output High Logic when the sound intensity reaches a threshold set by potentiometer

Features

  • A mounting screw hole 3mm
  • Module uses 5v DC power supply
  • Analog output
  • A potentiometer that adjusts threshold for digital output
  • high sensitive microphone
  • A Power indicator LED
  • An LED Signal Detect LED

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);
}
