3. Xebia Studio
4. Xebia Studio
5. Ground Floor Xebia Studio 1st Floor Mezzanine
6. Xebia Studio XL Room Lannister Room Stark Room Targaryen Room Meeting Room Toilet TV Xbox Hallway & Leisure Space Pinball Machine
7. Yes! A pinball machine!
8. A Day in Studio
9. 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
10. What about connecting the Studio?
11. IoT: What is it?
12. IoT: How big?
13. IoT: How much? Source : EMC, IDC, 2013
14. IoT: Why should I care?
15. IoT@Work
16. IoT@Work: How ?
18. Get Hands Dirty
19. MQTT \ Backend Architecture Overview Hardware Data Service Frontend Publish Subscribe Deliver Hardware Publish
20. Electronics
21. Hardware Nano Computer Micro Controller
22. Hardware • TI LaunchPad CC3200 + Platform Energia
23. Sensors Grove Temperature & Humidity Sensor Grove Motion Sensor Grove Sound Sensor
24. Sensors
25. Example: data lecture & publish #include <WiFi.h> #include <PubSubClient.h> #include <DHT.h> // PIN POSITIONS #define TEMP_HUMI_PIN 24 #define SOUND_SENSOR 6 #define LIGHT_SENSOR 2 #define ROOM_ID 1 DHT dht(TEMP_HUMI_PIN, DHT22); WiFiClient wifiClient; PubSubClient client(server, 16301, callback, wifiClient); char temp_buffer[256]; char humidity_buffer[256]; void setup() { // Setting up ... dht.begin(); } void loop() { }
26. 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() {}
27. Hack the Coffee Machine
28. Hack the coffee machine
29. Hack the coffee machine FC-51 Infra Red Distance Sensor

31. Communication Protocol
32. Why MQTT? • Invented in 1999 by IBM and Eurotech • Version 3.1.1 is now an OASIS Standard (Since November 2014) • mqtt.org
33. MQTT: light Pub/Sub model
34. Why MQTT? • Low overhead • Based on TCP/IP • Low energy consumption • Support of WebSocket • Different implementations: Java/Python/C++ • Commercial and Open Source version
35. Backend
36. 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
37. Elasticsearch Aggregation "aggregations" : { "<aggregation_name>" : { "<aggregation_type>" : { <aggregation_body> } [,"aggregations" : { [<sub_aggregation>]+ } ]? } [,"<aggregation_name_2>" : { ... } ]* }
38. Frontend
39. Frontend • Data Visualization • Data Pulling: auto refresh every 5min • Deployed on Github pages • Tools we love
40. MQTT Broker (Cloud- MQTT) Architecture Overview CC3200 Sensors (Meeting room) ElasticSearch (Bonsai Cluster) REST Service (Heroku Instance) FrontEnd Web Dashboard (Github Pages) Publish Subscribe Deliver Data Indexing Search & Aggregation CC3200 Sensors (Mezzanine) Publish
41. Difficulties
42. Difficulties • Newbies in electronics • Unstable Wi-Fi condition • Curiosity visitors • Time! Time! Time!
43. Dashboard

49. Next Steps
50. Physical Indications • Meeting room occupation sign • Button obsession ◦ Check-in button ◦ Croissant button • Hack the LED screen
51. Connected X • Connected Chairs • Connected Fridge • Connected storage for mobile device ◦ RFID + Monitor Screen ◦ Inventory Made Easy
52. iBeacons • Presence tracking • Information pushing
53. Data mining • Data analysis and correlation • Prediction
