A device that can eavesdrop on acoustic signals generated by the animals. Presented at ICFOSS Swathanthra Fifth International Free Software Conference, Kerala 18 - 20 December 2014, Hotel Hycinth by Sparsa, Trivandrum by Rineez Ahmed N To design a device that can eavesdrop on acoustic signals generated by the animals. System that is capable to record human audible acoustic signals generated by the animals from any remote area at customizable timings and duration without any manual intervention. The Recordings are formatted and stored properly with their timestamps and are uploaded to storage servers.

11. What the System is ?
System that is capable to record human audible acoustic
signals generated by the animals
from any remote area at customizable timings and duration
without any manual intervention.
The Recordings are formatted and stored properly with their
timestamps and are uploaded to storage servers.

13. How it Works ?
◈ 24x7 Active microcontroller switching circuit powers the
recording system on customized time defined by user.
◈ recording system on power up does the following
❖ Tries to Connect internet via usb modem
❖ Sync the real time from microcontroller / internet
starts recording and resumes the pending upload in
parallel with (if internet) for the user defined time
❖ after recording completion format it , attempt to
upload it
❖ Steps to Power off

14. ◈ Based on ATMega328.
◈ Programmed to provide power for recording system only
at scheduled timings.
◈ Uses DS1307 as an RTC as well as a storage for
scheduled power up timings.
◈ Communicates with the recording system , updates real
time from internet , stores user timings to DS1307
Microcontroller switching circuit (MSC)
Livares Technologies

15. ◈ Based on Raspberry Pi with a java application
◈ Records acoustic signals , connects to internet via usb
modem, updates real time of MSC ,updates the new
timing schedules from internet if available
◈ Uploads the recorded sound with time stamp to the
storage servers as mp3 - via ftp/sftp
◈ After Completion of recording request MSC to power off
the system then makes a safe turnoff of rasbian

16. ◈ Java application establish serial
communication with the microcontroller
switching unit and Raspberry Pi.
◈ Application logs all activities for future
investigation and maintenance.
◈ Establishes SFTP with storage server and
updates user timing schedules from internet
servers.

20. Acoustic emissions of animals contains species-specific and
individual information exploitable to listeners, monitoring it
constantly and deeply will reveal visually inaccessible habitats
that may open the key to the secrets of Biodiversity.
