Features:

  • Transistor Driven: Utilizes an S8550 transistor for effective sound signal control and amplification.
  • Wide Operating Voltage: Works reliably within 3.3V to 5V, supporting both 3.3V and 5V logic systems.
  • Compact Design: Small PCB size (3.3 cm x 1.3 cm) makes it easy to embed in tight spaces.
  • Easy Mounting: Includes pre-drilled bolt holes for secure and hassle-free installation.
  • Applications: Perfect for security systems, alert modules, and sound-based feedback systems.

Specifications:

  • Transistor: S8550
  • Working Voltage: 3.3V to 5V
  • PCB Size: 3.3 cm x 1.3 cm

How to Use with Arduino:

  • Connect the VCC pin of the module to the 5V or 3.3V pin of the Arduino.
  • Connect the GND pin to the Arduino GND.
  • Connect the signal IN pin to a digital output pin on the Arduino (e.g., D8).
  • Use digitalWrite(pin, HIGH) to turn the buzzer ON and digitalWrite(pin, LOW) to turn it OFF.

Example Arduino Code:


int buzzer = 8;

void setup() {
  pinMode(buzzer, OUTPUT);
}

void loop() {
  digitalWrite(buzzer, HIGH);
  delay(500);
  digitalWrite(buzzer, LOW);
  delay(500);
}
