A Day in Studio
A Day in Studio • Temperature differences • Surge of
noise level • Meeting room (a.k.a lunch room) occupied • Lights/TV left on • Coffee capsule shortage • Mobile device gone missing
What about connecting the Studio?
IoT: What is it?
IoT: How big?
IoT: How much? Source : EMC, IDC, 2013

Example: data lecture & publish #include <WiFi.h> #include <PubSubClient.h> #include

Example: data lecture & publish void loop() { // read
values from sensors & pubish to mqtt _temperature = dht.readTemperature(); _humidity = dht.readHumidity(); sprintf(temp_buffer, "{\"value\": %d,\"room_id\": %d}", _temperature, ROOM_ID); sprintf(humidity_buffer, "{\"value\": %d,\"room_id\": %d}", _humidity, ROOM_ID); if (client.publish("temp", temp_buffer) && client.publish("humidity", humidity_buffer){ log("Data published succeeded!"); } else { log("Data publish failed"); } delay(5000); } void log() {}

Communication Protocol
Why MQTT? • Invented in 1999 by IBM and Eurotech
• Version 3.1.1 is now an OASIS Standard (Since November 2014) • mqtt.org
MQTT: light Pub/Sub model
Why MQTT? • Low overhead • Based on TCP/IP •
Low energy consumption • Support of WebSocket • Different implementations: Java/Python/C++ • Commercial and Open Source version
Backend
Backend • Node.js app on Heroku ◦ Connect to CloudMQTT
via Websocket ◦ REST service using Express ◦ Index/Query Elasticsearch data • Data in ElasticSearch ◦ JSON over HTTP ◦ Data aggregation made easy
Elasticsearch Aggregation "aggregations" : { "<aggregation_name>" : { "<aggregation_type>" :
{ <aggregation_body> } [,"aggregations" : { [<sub_aggregation>]+ } ]? } [,"<aggregation_name_2>" : { ... } ]* }
Frontend
Frontend • Data Visualization • Data Pulling: auto refresh every
5min • Deployed on Github pages • Tools we love
