SKU: DF-SEN0232

The Gravity Analog Sound Level Meter is an Arduino-compatible decibel meter that accurately measures environmental noise levels. It uses an instrumentation-grade circuit with a low-noise microphone for high-precision readings across a 30–130 dBA range. The output voltage is linearly proportional...

SKU: LB-LR0240

This compact sound module lets a microcontroller detect the presence of loud sounds using its onboard microphone.It is designed for sound detection rather than audio recording or interpretation. An Arduino can read the module to respond to noise events, but it cannot directly interpret or record ...

SKU: PR-PIM356

Add sound to your micro:bit projects with noise:bit, a tiny speaker board made for bleeps, bloops, tones and speech.Just slot in your micro:bit and use the sound generation blocks and code in Microsoft MakeCode or MicroPython to create audio in your project. It is handy for simple sound effects, ...

SKU: DF-DFR0940

This power filter board for Raspberry Pi integrates solid capacitors, ceramic capacitors, and tantalum capacitors in a parallel hybrid filtering configuration. It filters low, mid, and high-frequency power noise from your supply, delivering cleaner power to the entire system — particularly benefi...

SKU: AF-2133

The Adafruit Audio FX Sound Board is a standalone audio trigger that plays WAV and OGG Vorbis files — no Arduino or programming required. Simply drag and drop sound files over USB, wire up buttons to the trigger pins, and you're ready to go. With 2 MB of built-in flash storage, it holds a few min...

SKU: DF-FIT0277

The DFRobot 12V Low Noise DC Motor (Model 28PA51G) is a quiet, high-torque geared motor with a built-in two-phase hall encoder. Designed for applications where noise is a concern, it produces approximately 57–68 dBA under no-load conditions — making it well suited for indoor robotics and equipmen...

SKU: SF-SEN-12642

The SparkFun Sound Detector is a small and very easy to use audio sensing board with three different outputs. The Sound Detector not only provides an audio output, but also a binary indication of the presence of sound, and an analog representation of its amplitude. The 3 outputs are simultaneo...
