Here’s my plan: Create a wireless Internet of Things device that records the sounds in my back yard and transfers time-stamped samples to a network attached storage device in my home office for analysis. I shall call this system the “Barkometer”
There are three parts to this plan, the first of which was assembling the hardware. As I’ve been extensively covering the Internet of Things and most particularly Raspberry Pi technology, I had a Raspberry Pi 2 Model B ($35 from Element14) to hand, so that was the obvious choice. Note that because high input data rates are required to handle audio, an RPi 3 Model B might have been a better choice as we will see later.
