High Sensitivity Microphone Electret Condenser Sound Sensor
Operating Voltage | 3-15V DC |
Board Size | 3.2 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.
For sound detection Module has two outputs:
The threshold-sensitivity can be adjusted via potentiometer on the sensor
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) ; } }
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) ; }
