HOW DOES IT WORK?

• Digital Mic keeps measuring sound level

• Level crosses the threshold, Node wakes up from sleep mode and starts sending audio measured from the analog mic.

• Audio is transferred on Digimesh using XBee modules from one to another.

• Audio reaches central receiver (raspberry pi)

• Samples recovered from serial data. MFCC matrix computed

• Matrix and metadata serialized and sent to cloud via TCP/IP socket

• Random Forest Algorithm is used to classify the bird's sound among common Indian birds.

• Bird found is displayed on a web-based map with its location.

• This Info. is written in a CSV file arranged into appropriate folders. Tree node goes to sleep.
