Voice-Activated Sound Detection Sensor Module – Analog Output, Low-Power Trigger Device

Description

Voice Sound Detection Sensor Module for official Arduino boards.

• For sound detection module has two outputs:
• There is a mounting screw hole 3mm
• Uses 5v DC power supply
• With analog output
• High sensitive microphone and high sensitivity amplifier
• A power indicator LED
• The comparator output is a LED

Here’s a simple sketch for testing: 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 {digital Write(Led LOW)}} 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); }
