KY-006 Passive Buzzer Module

The KY-006 Module is a Passive Piezoelectric Buzzer that can generate sound tones by repeatedly turning ON and OFF at a frequency of 1.5kHz to 2.5kHz, either using delays or PWM. It's compatible with a microcontroller, like Arduino, Raspberry Pi, and ESP32.

Here, you will get detailed information about this passive buzzer module circuit board, like specifications, pinout, circuit & connection diagram, and how to interface with Arduino.

KY-006 Module Specifications

KY-006 Module Circuit Diagram

Schematic of the ky-006 passive buzzer module circuit is shown below.

KY-006 Module Interfacing with Arduino

Connection diagram of the KY-006 passive buzzer module with an Arduino is shown below.

Connect the ground pin (-) and signal pin (s) of the ky-006 module to GND and digital pin 2 on the Arduino, respectively. The interface does not require the power (middle) pin of this module, as there are no internal connections.

Arduino Source Code

The following Arduino sketch for the KY-006 Passive Buzzer Module, set the signal pin of the module as the output. The module using this interface will generate a beep sound tone every 1-second delay.

#int PASSIVE_BUZZER = 2; // Define the Passive Buzzer Module KY-006 interface with Arduino
void setup() {
	pinMode(PASSIVE_BUZZER, OUTPUT); // Set Arduino pin as output
}
// Start the main program loop
void loop() {
	for (int i = 0; i < 100; i++) { // Make a Beep Sound Tone
		digitalWrite(PASSIVE_BUZZER, HIGH); // Buzzer is ON
		delay(1); // Delay 1ms
		digitalWrite(PASSIVE_BUZZER, LOW); // Buzzer is OFF
		delay(1); // Delay 1ms
	}
	delay(1000); // 1 second delay between ON and OFF signal
}
