- Versatile piezo-element module for both input or output
- Frequency response: 0-20KHz
- Sound pressure level at 10cm: 75dB (min)
- Built-in 1M resistor for knock sensor functionality
The Sound and Buzzer Module can be used as a noise-maker driven by your microcontroller for audible feedback of events, and it can also be used as a knock-detector input to sense events and react to them.
