Outcome

I was successfully able to trigger my phone to play Lithium (Nirvana), by walking near the motion sensor. The motion sensor can be placed horizontally or vertically, providing a lot of possibilities in it's placement and encasement design. While the Yellow LED would blink every time, motion was detected, I had trouble getting the Red LED to stay on, I assume this is because it doesn't have enough voltage.

 Ideally the device should trigger a radio channel on the Sonos system in our home. Due to the limitations in the IFTTT action portfolio, I could only play a specific song within my device.

A great deal of programming has to be customized depending on the final source of audio. The Sonos controller for example can only be played via an android device.
