Sensor

• What it senses
• Home Monitoring
• Health Monitoring
• Environment Monitoring
• Habitat Monitoring
• Earthquake Monitoring
• Battlefield Monitoring
• ?Sensors exist everywhere
• ?Monitoring of physical world its phenomena
• Additional Features
• Data Processing
• Communication
• within Low-Power Constraints

12
Cellular Phone

• Main Function
• Mobile Phone to connect people
• Additional Features
• Message Service
• Camera and Camcorder
• Multimedia Playback
• with powerful computing and infrastructure-based
  network
• Battery-operated
• Roles for Sensors
• A bunch of sensor nodes
• A central node or a proxy server for sensor
  network
• A terminal to human for sensing data

13
A. Cell Phone as a Sensor

• To collect, to process, and to distribute data
  around people
• Home Care
• scan environmental data and forward it to care
  center
• e.g.) check the gas leakage or poisonous material
  
• Health Care
• sense users health status and update/keep it.
• e.g.) keep the heart rate or blood sugar rate for
  diabetics
• Emergency Care
• catch the emergent situation around people and
  scan/send data
• e.g.) send rescue calls and captured data like
  picture

14
A-2. Health Care

• People want to check their health simply
• LG KP8400 Diabetics Phone
• Blood Sugar Testing Phone
• place a strip of testing paper located near
  battery
• place a drop of blood on the end of the strip
• get a reading from the phone
• upload to an online database for later retrieval
• ? Mobile Handset provides tools to check our
  health status and to keep or accumulate it

15
A-2. Health Care (cont)

• What else for heath care?
• Very basic but important health care services
• NONIN Onyx 9500 Digital Finger Pulse Oximeter
• Read data over fingertip
• Real-time information on Heart-Rate and Blood
  Oxygen Saturation Level
• ? Simple devices for health care can be converged
  into mobile phones to check the health by user

16
A-3. Emergency Care

• Cellular phone carries rescue button call for
  safe
• Curitel PG-L5000 SOS Phone
• Emergency Button Call
• Call at three saved numbers
• Take two pictures and send them
• Inform others of the position using GPS
• ? Mobile Handset senses emergent data

17
B. Cell Phone as a Proxy

• To use computing power and communication ability
  of cell phones for sensor network like a Proxy or
  a central node
• Offloading technology
• CPU1s MHz in Sensor VS 100s MHz in Cell Phone
• e.g.) sensor captures images and cell phone
  encodes/encrypts them and transmits them.

18
C. Cell Phone as a Terminal

• A terminal to human for sensing data
• User can get information from sensor network
  immediately after requesting
• An interface to human for information
• User can collect preferred data through cellular
  phone

19
C1. Security

• Cellular phone scans users fingerprint
• LG LP-3800 with Fingerprint Scanner
• AuthenTech sensor for fingerprint recognition
• Locked for unwanted user to use the phone
• ? Mobile Handset recognizes unique data for
  personal security

20
C-2. Code Interface
1
2

• Colorzip.com "ColorCode" - an interface
  connecting you to online contents
• Media provides ColorCode
• User camera on phone recognizes it
• Server provides contents to client
• User enjoys the contents
• ? Mobile Handset provides an interface like
  camera to read and process data

21
Wrap-up

• Cellular Network might be a huge-covering and
  very potential Sensor Network.
• More Friendly and Closer to Human Being
• Mobile Handset has an interface for sensing data
  and functionalities of computing and
  communication
