Adding microphone to QWIIC setup

Qwiic System
1

Hi,

I am working on a simple sensor setup.

I need a calibrated Microphone that can

Measure SPL

Make a 5 band measurement of sound levels at different HZ intervals

A CO2 / temperature / humidity sensor

SCD40 Works fine!

I’ve used the SCD40 with a SparkFun DataLogger IoT - with custom code. This works perfectly - and I love the easy QWIIC connector.

My question is.

How can I add a calibrated MIC with this setup - I cannot find a QWIIC enabled calibrated MIC?

Making use of a calibrated mic might be the tricky part…but if you’re loading custom code already, in theory you could use something like this https://www.amazon.com/miniDSP-UMIK-1-M … B00N4Q25R8 and pass it through the USB port on the IoT board https://cdn.sparkfun.com/assets/e/3/d/7 … ic_v11.pdf and finally throw the readings to an SD log

Let us know if you get it going!
