High Sensitivity Sound Microphone Sensor Detection Module

High Sensitivity Sound Microphone Sensor Detection Module เซนเซอร์เสียง

เซนเซอร์เสียง ให้สัญญาณแบบ analog และ digital สามารถปรับความไวได้

ข้อมูล High Sensitivity Sound Microphone Sensor Detection Module เซนเซอร์เสียง

For sound detection module has two outputs:

1. AO analog output, real-time output voltage signal of the microphon

2. DO when the sound intensity reaches a certain threshold, the output high and low signalModule

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

ตัวอย่างการใช้งานแบบ 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)
}
}

ตัวอย่างการใช้งานแบบ 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);
}
