• Proximity & Presence • Weight • Liquids & Liquid flow • Radia;on • …
Sensors & Actuators
• Move things (motors) • Ac;vate (switches) • Interfaces
– Sound – Light – Displays
• Remote interfaces – Social – Email, text, … – Phone (twillio)
Soiware
• Standard IDEs – Arduino IDE – Eclipse
• Code – less: – Scratch
• Cloud-‐based – Codebender (codebender.cc) – par;cle.io
• Browser-‐based – mBed – Electron – Noduino – …
Workflow -‐ based
• Node-‐RED

IoT & JavaScript
SoEware • Noduino • A simple and flexible JavaScript and Node.js Framework for
accessing basic Arduino controls from Web Applica;ons using HTML5, Socket.IO and Node.js
IoT & JavaScript
SoEware • Device.js • DeviceJS is a JavaScript based development plaHorm for
reac;ng to sensors and controlling devices. It’s built on top of Google’s V8 JavaScript engine, Node.js and a real-‐;me JSON database
IoT & JavaScript
SoEware • Node-‐RED
– Node-‐RED is a tool for wiring together hardware devices, APIs and online services
– Web-‐based – O/S

Sensor Communica;on Technologies
MQTT WebSockets
XMPP … Service Discovery
Security
IoT PlaLorm As A Service
COMPOSE at heart
servIoTicy • IoT Streaming made easy! • RESTful API for:
– Storing device (sensor) data – Querying & Retrieving the data – Pushing data to the device – Subscribing to no;fica;ons (e.g., new sensor data arrived)
• Free and Open Source • Downloadable bundle (Ubuntu/Debian Image) • Soon -‐> CloudFoundry installa;on
WWW -‐> IoT CoAP
REST
MQTT CoAP
