Small electret microphone. Useful in acoustic and audio applications.

FT-MIC

Give your project ears with this sound response and sound pressure level sensing module. An integrated dual signal amplifier converts the sound to separate channels for pulse / frequency measurement, and sound volume (pressure) level. Designed to connect straight to an Arduino...

AF-3367

Hey, listen up! It's the world's smallest USB microphone! OK maybe it's not in the Guinness Record Book, but it is pretty darn small! This plug-and-play Mini USB Microphone needs no driver, and its USB interface means you can use it with any computer, laptop, SBC, etc!

AF-1935

That's one tiny microphone! At about the size of a mature aphid, this wired Electret Microphone is perfect for your FONA.

AF-1063

Add an ear to your project with this well-designed electret microphone amplifier.

AF-3421

Listen to this good news - we now have a breakout board for a super tiny I2S MEMS microphone. Just like 'classic' electret microphones, MEMS mics can detect sound and convert it to voltage, but they're way smaller and thinner. This microphone doesn't even have analog out, its ...

PL-1620

Ready to add sound detection to your next project? This compact breakout board from SparkFun couples a small electret microphone with a 100x opamp, converting sound into amplified analog voltages that can be measured by a microcontroller’s analog-to-digital converter (ADC). ...

SU-TS0223

The sound sensor has a built-in capacitive electret microphone which is highly sensitive to sound.

DF-SEN0045

This Breakout Board is Discontinued Now, We recommend Sound Sensors as a suitable replacement.

SF-COM-13316

Do you make time to talk to your Arduino? Maybe you should! The EasyVR Shield 3.0 is a voice recognition shield for Arduino boards integrating an EasyVR module. It includes all of the features of the EasyVR module in a shield form factor that simplifies connection to the Ardui...

DF-DFR0042

This tiny breakout board features the ADMP401 MEMs microphone. One of the key advantages to this breakout and microphone is the bottom ported input. This means the microphone's input can fit flush against the enclosure of your project. Plus you will not have to deal with tryin...

DF-SEN0232

This is an Arduino compatible sound level meter(also known as decibel meter, noise meter). It uses instrument circuit, low noise microphone, which make it accurately measure the sound level of the surrounding environment. It can be applied to environmental noise testing, such ...

AF-1739

This large (30mm diameter) piezo element is nicely enclosed with mounting holes so you can attach easily. Piezo elements convert vibration to voltage or voltage to vibration. That means you can use this as a buzzer for making beeps, tones and alerts AND you can use it as a sen...

AF-176

An assortment of the most common sensors used in electronics. 9 sensors and 3 additional components to interface with the 'analog world'. We have some tutorials here, to get you started.

AF-3492

An exotic new microphone has arrived in the Adafruit shop, a PDM MEMS Microphone! PDM is the 'third' kind of microphone you can integrate with electronics, apart from analog or I2S. These microphones are very commonly used in products, but are rarely seen in maker projects. St...

INTRODUCTION

AF-160

Piezo buzzers are used for making beeps, tones and alerts. This one is petite but loud! Drive it with 3-30V peak-to-peak square wave. To use, connect one pin to ground (either one) and the other pin to a square wave out from a timer or microcontroller. For the loudest tones, s...

AF-1713

Add an ear to your project with this well-designed electret microphone amplifier with AGC. This fully assembled and tested board comes with a 20-20KHz electret microphone soldered on. For the amplification, we use the Maxim MAX9814, a specialty chip that is designed for amplif...
