Description
The Active Buzzer Module features a built-in oscillation circuit that generates a fixed-frequency sound automatically when powered. Unlike passive buzzers, it does not require an external signal or PWM input, simply apply a DC voltage and the buzzer will emit a continuous tone.
Key Features
- Built-in Oscillator: Produces sound automatically when powered
- No External Signal Required: No PWM or frequency generation needed
- Simple Digital Control: Can be switched ON/OFF using a microcontroller pin
- Wide Compatibility: Works with Arduino, ESP32, ESP8266, Raspberry Pi, and other boards
- Low Current Consumption: Suitable for direct microcontroller output
- Easy Mounting: Pre-drilled bolt holes for secure installation
- Compact Design: Ideal for tight project spaces
Specification
- Operating Voltage: 3V – 5V DC
- Current Consumption: Low (safe for most GPIO outputs)
- Tone Type: Fixed-frequency continuous beep
- Interface:
- VCC: Power input (3–5V)
- GND: Ground
- Control Method: Digital HIGH/LOW signal
Application
- Alarm systems
