Active Buzzer module
An active buzzer module comes with a built-in oscillation circuit, meaning it produces a fixed-frequency sound on its own. It doesn’t require a signal to generate tones—just a DC power supply. You can easily control it using a digital pin on an Arduino, similar to how you would turn an LED on or off. Once powered, the buzzer automatically emits a beeping sound.
Features:
- Active buzzer design– generates a continuous tone automatically when powered (no external signal or PWM required). Simply apply a DC voltage to activate sound.
- Versatile compatibility– suitable for use with Arduino, ESP32, ESP8266, Raspberry Pi, and other microcontrollers
- Easy mounting– includes pre-drilled bolt holes for secure installation in various applications (e.g., panels, robots, enclosures)
- Compact design– fits well in tight project spaces
Specifications:
- Operating Voltage:3V to 5V DC
- Current Consumption:Low (suitable for direct microcontroller output)
- Interface:
- VCC– Power input
- GND– Ground
