Audio Sensor Arduino Compatible

Arduino compatible Audio Sensor


1 $5.95


This sensor features a microphone for detecting sound. It features both a digital and an analog output. The analog pin outputs a real-time voltage signal of the microphone. The digital pin gives either a high or low signal indicating when sound intensity has reached a certain threshold. The sensitivity threshold can be adjusted via the potentiometer on the sensor.

Test Code

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

// When the sound detection module detects a signal, LED flashes
if (val == HIGH) {
digitalWrite (Led, HIGH);
else {
digitalWrite (Led, LOW);


  • Detect sound intensity
  • Digital & analog outputs
  • Sensitivity threshold can be adjusted via potentiometer
