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
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
