Description
The KY-006 Passive Buzzer Module is a compact sound-generating component perfect for adding audio output to your Arduino, Raspberry Pi, or other microcontroller projects.
Unlike active buzzers, this passive buzzer allows you to control the frequency and duration of tones, making it ideal for beeps, alarms, sound effects, or even simple melodies.
This module is ideally suited to adding sound notifications, status alerts, or interactive audio feedback to your electronics projects.
The small form factor makes it easy to integrate into breadboards and embedded systems while keeping wiring simple with its 3-pin interface.
Microcontrollers like Arduino can easily control this buzzer using tone-generating libraries and the tone() function.

What’s Included:
- 1x KY-006 Passive Buzzer Module
Great For:
- Audio Alerts in Arduino/RPi Projects
- Creating Melodies or Beep Patterns
- Timers, Alarms, & System Notifications
- Interactive DIY Projects & Interfaces
- Education, Prototyping & STEM Kits
Usage Tips:
- Use tone(pin, frequency) in Arduino to generate sound
- Stop sound with noTone(pin)
- Requires PWM or tone signal – does not work with direct HIGH/LOW only
- Best used with a current-limiting resistor if needed for precise tones
- Want a fixed-tone buzzer? Try KY-012 (active version)
