Microphone Voice Sound Sensor Detection Module For Arduino AVR PIC Analog Digital Output Sensors KY-038 KY-037

Package : SMDis_customized : YesModel Number : KY-037Operating Temperature : 11Dissipation Power : 5vSupply Voltage : KY-037Application : AlarmCondition : NewType : Voltage RegulatorBrand Name : baishundianzi : Mainland ChinaFor sound detection module has two outputs:1. AO, analog output, real-time output voltage signal of the microphone2. DO, when the sound intensity reaches a certain threshold, the output high and ?low signalModule features:1. there is a mounting screw hole 3mm2. the use 5v DC power supply3. with analog output4. there are threshold level output flip5. high sensitive microphone and high sensitivity.6. a power indicator light7. the comparator output is lightDigital Output:int Led=13;//define LED ?interfaceint onpin=3 //Define D0 Sensor ? Interfaceint val;//define numeric variables valvoid setup(){pinMode(Led,OUTPUT);// Define LED as output interfacepinMode(onpin,INPUT);//Define D0 Sensor as output Interface}void loop(){val=digitalRead(onpin);//digital interface will be assigned a value of 3 to ?read valif(val==HIGH)//When the light sensor detects a signal is interrupted, LED ?flashes{digitalWrite(Led,HIGH)}else{digitalWrite(Led,LOW)}}2.Analog Output:int sensorPin = A5; // select the input pin for the potentiometerint ledPin = 13; // select the pin for the LEDint sensorValue = 0; // variable to store the value coming from the sensorvoid 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);}Microphone Voice Sound Sensor Module For ArduinoThis is microphone voice sound sensor module for ArduinoModel: KY-038Adopt LM393 main chipElectric condenser microphoneFeatures Single channel signal outputLow level output signal used for sound control lightGreat module for sound alarm systemWorking voltage: For DC 4-6VInterface definition:AO: analog output sensorGND: groundVCC: Power supply input range: 3V-24V.DO: Digital Output (comparator output)Two red LED indication: POWER and SENSOR. POWER: Power is off. SENSOR:When the microphone senses sound reaches a certain value, this LED light.Package included:1 x Voice sound sensor module
