Overview

• Cellular phone is a widespread device. Its
  availability and its friendly usage make the
  cellular phone inseparable part of our personal
  items.
• Today cellular phone is used with wide range of
  SOFTWARE applications like communication, SMS,
  diary, games, music, multimedia etc.

3
So what's the problem?

• unstoppable technology progress.
• client that likes to extend its cellular phone
  capabilities, must purchase an advanced model of
  cellular phone with integral hardware and
  software.
• demand for accessory device which enable his
  owner to operate new applications and the ability
  to adjust them according to owners will.

4
Project Goals

• Design and implementation an independent generic
  device which can function as a host platform of
  various applications for cellular phone.
• Key futures
• Generic and versatile
• Multi compatibility
• Size - key ring format
• Multi purpose hardware - Microcontroller, FM
  receiver, Thermometer etc.
• Power source - cellular battery, low voltage
  supply
• I/O - using the cellular LCD , Keypad
• Communication interface - connectivity to PC for
  configuration

5
Project Goals (continue)

• In order to exemplify the general concept we
  intend to implement prototype device.
• Base on integral abilities can perform the
  subsequent applications
• DISTREES BUTTON
• INFRA RED ALARM SYSTEM
• THERMOMETER
• ELECTRONIC SWITCH
