The API of Things, APIs, APIs all the waydown

motivation I
B Internet of Things (IoT) is amisnomer
B it should be called the API of Things (AoT) —everything runs on APIs
B from the sensors to the analysis of the data theyprovide
internet of hipster junk
B tweeting fridge from LG — added value ≈ 0
context I
B relayr is a company that focuses on this great chain ofAPIs as the IoT enabler
B we approach IoT end-to-end: from sensors to dataanalysis
context II
B from the sensors ...
context III
B ... to the data analysis
motivation II
B many protocols are used: MQTT, CoAP, HTTP,WebSockets, &c
B the modern protocols are open and fully standardized— APIs are built upon them
B that’s where the value comes from: munging the datastreamed via those APIs
hardware commoditization
B IoT usually lingers almost to the exclusion ofeverything else in hardware
B on the other hand hardware is becoming a commodity
B hardware is but a tool: it’s what you craft with this toolthat matters
walking the walk I
B We’ll build a noise sensing device that publishes datato the relayr cloud via MQTT
B we’ll show that the value is extracted through the APIsbeing used, not the hardware
walking the walk II
B noise is a major health and environmental issue — theworld has become progressively noisier
B silence is a rare and valuable commodity

the plan
B using the Olinuxino A13 with the onboard audio codecfor capture
B using sox to capture a noise sample and analyze it
B publish data via MQTT to the relayr cloud with themosquitto client
demo time
going further
B use a microphone array withmultiplexing done viaanalog switches
B use MQTT over SSL for added security
B use the data outside of the relayr cloud for fineranalysis
B use an electretmicrophone capsule with a low noisepreamplifier
