  1. SECE: Sense Everything, Control Everything Prototype Sensor and Actuator I Presented by Hyunwoo Nam R T Internet Real Time Lab

  2. The big picture “Prototype sensor/actuator for devices that are not IP-capable” RFID Alice  a@b.com, +1 212 555 1234 Presence Server SECE GW I control appliances PUBLISH PIDF-LO SUB/NOT .. R T edit scripts update SNs, SMS, email call state Geocoding travel time B2BUA monitor energy usage “SECE allows non-technical users to create service that combine Communication, Calendaring, Location and Device in the physical world. ” Internet Real Time Lab

  3. The Arduino • $21 • Programming Environment (C language) or AVR-Studio • Easy to start with • Phidgets, X10, Zigbee available • Huge community • Software development on Mac OS-X and Windows • How to connect to the Internet? I R T Microcontroller: ATmega328 Operating voltage: 5v Flash memory: 32KB SRAM: 2KB EEPROM: 1KB TCP/IP stack built in “ Arduino Ethernet shield (stackable) ” Internet Real Time Lab

  4. Appliances controlled by Arduino “ Control Lamp using Arduino ” I Arduino IDE USB/Serial Arduino R T X10 Lamp Module X10 PLC Controller RJ11 Cable X10 power line signal Internet Real Time Lab

  5. Appliances controlled by Arduino (continue) SECE server “ Control IR Electronics ” -SAMSUNG: TV, AUDIO.. -LG: TV, PROJECTOR.. IR standard table • LG • - TV_ON:0x8A75F20D • - TV_OFF:0x5A63B203 • SAMSUNG • - AUDIO_ON:0x8A75F20D • AUDIO_OFF:0x5A63B203 • .. SECE users I 0x8A75F20D R T IR Electronics The Internet 0x8A75F20D IR LED Arduino Internet Real Time Lab

  6. Communication with SECE server SECE SERVER SECE USER DHCP LAMP ARDUINO Get IP address Turn on Arduino && Button pressed DNS Get SECE server IP address using Hostname I R T TCP/IP Webscoket handshake via HTTP Update DNS User login OAuth Token Stored in EEPROM Turn on lamp POST /lamp?v=100 HTTP/1.1 Auth.token Send X10 Signal JSON Format Internet Real Time Lab

  7. Conclusion Achievements • Implemented a set of Arduino libraries for SECE project • Can control Arduino from SECE server over the Internet • Can control other commercial modules (Phidgets/X10/Infrared) via Arduino • Can communicate with Zigbee modules for location tracking system I R T Future works • Implement OAuth communication between Arduino and SECE server • Discover individual sensors from Arduino  - figuring out what types of sensors are connected to a particular Arduino and naming them• Setup permissions for individual sensors - public, private, shared within a group, etc..
