Microphone Module I2S Interface Case

thingiverse

I made this to house this microphone module... https://www.ebay.com/itm/Omnidirectional-Microphone-Module-I2S-Interface-INMP441-MEMS-Low-Power-for-ESP32/274119515372 I'll be putting it underneath a bee hive to listen for swarm indications.

Of course trim off the excess, maybe put a wrap of electric tape on the seam. The stem is made for a 3/8" hole (10mm). Here's some Pi enclosures to use it with. https://www.thingiverse.com/thing:3970641 https://www.thingiverse.com/thing:3894010 Follow the adafruit tutorial (I didn't do the rpi-update).... https://learn.adafruit.com/adafruit-i2s-mems-microphone-breakout/raspberry-pi-wiring-and-test Then you can use the command cvlc -vvv alsa://dmic_sv --sout '#transcode{acodec=ulaw}:rtp{sdp=rstp://:8554}' to stream audio available at vlc rtsp://your.Pi.IP.address:8554/ You will need to install VLC media player on the Pi. This module will not work if Pigpio is running. I think it can be fixed to where they will work together, but I haven't tested it yet.
