INTERACTING WITH THE REAL WORLD

Sunday, 24 June 12

INTERACTING WITH THE REAL WORLD

• The Internet Of Things ...

• Billions of small, low-powered, network connected devices

• Sensors, e.g light, temperature, water flow, electrical current

• Actuators, e.g. turn on/off, open/close, adjust, move

• Becoming more prevalent ...

• Low cost, open source hardware and software design

• Ubiquitous networking: 3G, Wi-Fi, Bluetooth, ZigBee (mesh)

ARDUINO OVERVIEW

Sunday, 24 June 12

ARDUINO OVERVIEW

•Arduino controller ...

•Low cost

•Easy to use (program and operate)

•Flexible (different sizes and capabilities)

•Large and active community

•Open-source (everything visible and changeable)

•Vast range of affordable sensors and actuators available

•Hobbyist and commercial ecology (both important)

ROUTER DETAILS

Sunday, 24 June 12

ROUTER DETAILS

• Common Off The Shelf (COTS)

• Cheap: Astonishing what you get for AUS$50

• Comms: 4 + 1 Ethernet ports, Wi-Fi, serial console

• USB ports: expansion ... disk, printer, 3G

• OpenWRT (Linux distribution): Many packages

• Highly hackable :)

PROTOCOLS

Sunday, 24 June 12

PROTOCOLS

• Low-power devices and networks need small messages

• MQTT (Message Queue Telemetry Transport)

• Connect, Publish, Subscribe, Ping, Disconnect

• Topics

• Asynchronous messages

• Last will and testament (in case of failure)

• Aiko platform: Software for the Internet of Things (M2M)
