Made for/with the PNCA Sensing the Environment Project.
This is a sound recording and reporting kit. Right now, sound is recorded to an onboard SD card. Stage 1 will send this info over Wifi to a Python server on a host computer.
- record bird songs at night for as long as possible (1-2weeks)
- transmit bird songs to cloud server after recording is finished (during the day)
- connect to cloud server to download recorded data
- make a recording device that is cheap and easy to setup and maintain
For the Rpi:
- Image of RPi_sensing (TODO: make and post image of pi with everything configured proper)
For the computer:
- Python 2.*
- Virtualenv & virtualenvwrapper
- pip
- a python script takes care of sending files to ftp server on a schedule
- a built-in linux program called arecord takes care of recording data on a schedule
- a shell script takes care of recording intervals and generating Pi-specific (using MAC address) filenames
- witty pi software and hardware takes care of sleep/wake schedules
You will need: -[Raspberry Pi 3 model B] -[Sabrent USB sound card adapter] -[Sparkfun Sound Detector or Adafruit Amplifier] -[Witty Pi 2 Cape for Rpi] -[microSD card (8GB is fine)] -[USB thumb drive (128GB)] -[Waterproof enclosure ] -[small waterproof gland (for microphone) PG7] -[medium waterproof gland (for AC power) PG9] -[Minimum 2.1A 5VDC power supply] -[AC extension cord] -[shielded microphone cable ]
Optional accessories : -[HDMI cable], -[HDMI monitor], -[USB keyboard] -[USB mouse]
- [Wireless dongle w/ removable 5dB antennae that works with Pi(optional) (enhancement for larger range)] -[Hardware for standoffs] -[acrylic sheets for mounting plate (enclosure)]
An SFTP server installed on an Intel Nuc will live at Dylan's place
An SFTP client install on the Rpi lives in the field
On the raspberry pi, follow the setup on raspberry pi audio setup
then test recording with:
arecord -f S16_LE --r=22000 -D plughw:1 --max-file-time 30 --duration=10 -vv ~/rectest11.wav
the witty pi software uses a script to control when to go to sleep and wake up found in /wittypi/schedules/
edit the etsyhost name to be unique:
- sudo nano /etc/hosts
duration is the maximum length of chunks in seconds
max file time is the ultimate length of recording in seconds
On the host computer, in the project directory, run the following commands to set up your Python environment:
mkvirtualenv sensing
pip install -r requirements.txt
This should install pyserial locally in your sensing virtual environment.
run brew install sox to get SoX on your computer.
To work in your virtualenv, run the command workon sensing. To leave, run deactivate.

- download latest version of NOOBs or Debian Jessie/Wheezy
- update software
- configure keyboard, locale, and timezone as US.
- clone this repo
- run python script as a bash script on startup
- follow raspberry pi audio setup to make sure you can record with your setup
