Sound Detection Module(KY-037): 두 판 사이의 차이

2025년 3월 21일 (금) 16:27 기준 최신판

The Sound Detection Module (KY-037) is a compact and versatile sensor designed for detecting sound levels in the environment. It's commonly used in projects that require noise or sound detection capabilities, such as voice-activated systems, security alarms, or environmental sound monitoring.

Specifications

Operating Voltage: 3.3V ~ 5V
Output Type: Digital, Analog

Connection

The circuit utilized in the example code below.

An LED can be replaced with another module or omitted entirely.

Resistor	Sound Detection Module	LED	Arduino
	VCC		5V
	GND	-	GND
Connection		+
	DO		D8
Connection			D7

Example Code

// Code that lights up the LED when the module detects sound.
#define led_pin 7
#define sound_pin 8

float state = 0;

void setup() {
  pinMode(led_pin, OUTPUT);
  digitalWrite(led_pin, LOW);
  pinMode(sound_pin, INPUT);
}

void loop() {
  state = digitalRead(sound_pin);
  if (state == 1) {
    digitalWrite(led_pin, HIGH);
    delay(500);
  } else digitalWrite(led_pin, LOW);
}
