Sound sensors

Sound sensor is a module converting acoustic waves into electrical signal. In very simple terms, sound detectors work based on capacitance changes caused by sound wave vibration. Air vibration moves the diaphragm in the microphone causing capacitance change in the coupled capacitator. Capacitance change than gets amplified by module (LM386, LM393 or MAX9812L to name some currently in our offering) resulting in signal read. Check out all our microphone modules!

SparkFun MEMS Microphone...

SP021

SparkFun MEMS Microphone Breakout - INMP401 (ADMP401)

Ever needed a microphone for your project. This tiny little board will fulfill all your needs - it is not only mobile, but as well easy to connect. A low power, efficient, omnidirectional AMP401 microphone has an analog output. It works great for near and long range uses and is particularly suitable for a mobile projects given its extremely low energy consumption. You can use it in a range of applications - we can see it used in smartphones, cameras or electronic nannies.

MAX9812L Amplified...

M0151

MAX9812L Amplified Microphone for Measuring Sound

The MAX9812 is a sound amplifier specially designed to treat the signal coming from microphones.
We can use it together with Arduino to measure sound from a processor like Arduino.
When we saw the modules with microphone we commented that, in general, the signal generated is too low to be registered correctly.
If we want to be able to measure sounds, we will have to amplify the signal. The MAX9812L has single / dual inputs, fixed gain of 20dB, bandwidth of 400 kHz, low noise and low signal distortion 0.015% THD.
There are two models, its supply voltage is 2.7V to 3.6V.
We can use the sensors with MAX9812 for applications that require measuring the intensity or frequency of the sound.
