## Description

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 compatible microcontroller, Analog to Digital converter, or many other circuits.   *Click here for the Microphone Sound Input Module Quickstart Guide* 
  The two outputs provide independent access to either the raw signal waveform (the MIC output) or the sound pressure level (the SPL output) to provide maximum flexibility in your projects. If you want to process the audio waveform directly you can use the MIC output, or if you just want to detect sound level (for example, to detect noise above a certain threshold) you can use the SPL output. The module also includes a handy green LED as a "DETECT" display connected to the SPL channel, giving you immediate visual indication when the module is detecting sound.- Omnidirectional microphone
- Frequency response 60Hz to 15KHz
- Sensitivity -40dB typical
- Dimensions: 23(W) x 16(H) x 8(D)mm
 
The module includes mounting holes suitable for M3 or 1/8" bolts.

Available here or at a Freetronics reseller near you.
