industrial SoundSensor

Microphone

Now (Nov 18) available: industrial microphone for heavy-duty industrial applications.

 

 

 

 

 

 

The microphone comes with no pre-amplifier and needs biasing 2-10V DC from 2,2kΩ source. Pre-amplifiers can be customized (A- or C- characteristic)

Codec

Next, we will develop a SoundSensor solution based on the microphone and an industrial codec.

 

 

 

industrial codec will be cable-bound and heavy duty.

In terms of protocol we are still investigating. I-O LINK is number one, currently.
