Short Product Description
Short Product Description
Looking to add custom melodies, alert tones, or UI feedback to your next STEM project? The KY-006 Passive Buzzer Module puts you in complete control of pitch and tone. Unlike standard active buzzers that emit a single sound, this programmable module lets you generate distinct musical notes using a PWM signal. Compact, highly responsive, and perfect for Arduino or Raspberry Pi builds, it’s the ultimate audio component for hobbyists and engineers alike.

Bring Your Electronics Projects to Life with Custom Sound
Whether you are building a smart home security system, a DIY weather station, or an interactive STEM toy, auditory feedback is crucial. The KY-006 Passive Buzzer Module is engineered to deliver clear, customizable audio outputs, transforming a silent circuit board into an interactive experience.
Complete Tone Control (Passive vs. Active Buzzers)
Not all buzzers are created equal. Active buzzers have internal oscillators that restrict them to a single, continuous beep. The KY-006 is a passive buzzer, meaning it relies on external Pulse-Width Modulation (PWM) signals from your microcontroller (like an Arduino or ESP32). This gives you the creative freedom to manipulate frequencies (between 1.5kHz and 2.5kHz) to play specific musical notes, complex melodies, or varying alarm sirens.
Engineered for Versatility and Efficiency
Operating on a wide voltage range of 1.5V to 15V, this module easily adapts to both low-power microcontroller logic and higher-voltage industrial setups. With a working current of <25mA, it provides excellent sound volume without draining your power supply, making it ideal for battery-operated IoT devices.

FAQ Section
FAQ Section
Q: What is the difference between the KY-006 passive buzzer and an active buzzer?
A: An active buzzer makes a sound as soon as power is applied, but it only plays one tone. The KY-006 is a passive buzzer, meaning you need to provide a PWM (Pulse-Width Modulation) signal to generate sound. This allows you to control the pitch and play different musical notes.
Q: Do I need a resistor to connect this to my Arduino?
A: The KY-006 module typically has an onboard resistor, allowing you to connect the signal pin directly to a PWM-capable digital pin on your Arduino or Raspberry Pi safely.
Q: Can I pick this up today and get help with the code?
A: Yes! You can choose local pickup at checkout and collect your order directly from our physical store in Sham Shui Po. Our team is always happy to offer basic technical pointers to get your project running.
