KY-037 - Geräuschsensor
KY-037 - Geräuschsensor
Einführung
Das Modul hat zwei Betriebsarten für die Ausgabe:
-
AO, analog output der Signalstärke
-
DO, schaltet bei einem einstellbaren Schwellwert
The threshold-sensitivity can be adjusted via potentiometer on the sensor

Beispielcode
int Led = 13 ;// define LED Interfaceint buttonpin = 3; // define D0 Sensor Interfaceint 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); } } //Analoge Ausgabe }
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);} // - Zugriffe: 237
