This sound sensor with microphone that can be used for the Arduino, among other things, lets your circuit detect sound. When sound is detected, the output will go from 1 to 0. With the adjustable resistor on the board, you can set the sensitivity.
With an LED that indicates whether sound has been detected.
Supply voltage: 5V
Dimensions: 32mm x 17m...

Just like 'classic' electret microphones, MEMS mics can detect sound and convert it to voltage, but they don't need a bias resistor or amplifier, its all in one! The SPW2430 is a small, low cost MEMS mic with a range of 100Hz - 10KHz, good for just about all general audio recording/detection.
This breakout is best used for projects such as voice c...
