Agenda

• Introduction– sun SPOT project– sun SPOT device

• Sensors• Sun-SPOT

Development• Applications• Conclusions

What is project SUN-Spot?

• Initiative of Sun-labs

• an open-source technology.

• Aimed at exploring next-generation Networking

• completely Java based

What is a Sun SPOT Device?

• It is a small, wireless, battery powered experimental platform.

• Embedded Sensors.

• Programmed almost entirely in Java

• No specialized embedded system development skills required.

SunSPOT Device

• Sun SPOT uses J2ME which it runs directly on the processor without an OS.

• Standard Java IDEs (e.g. NetBeans) can be used to create SunSPOT applications.

• Regular programmers can create projects using sun-spot easily.

Sun SPOT Hardware

Sun SPOT Hardware (sensors)

Sensors

• accelerometers• light detectors• temperature sensors• LEDs• push buttons • and general I/O pins.

Accelerometer

• The accelerometer can be used to measure the motion of the SPOT.

• It can also measure the SPOT‘s orientation with respect to gravity.

Temperature Sensors

• The temperature sensor is the simplest of the sensors.

• The temperature can be read in Celsius or Fahrenheit.

• Range (-40 ° C to +125 ° C)

• Actually, it is the reading of the sensor board.

• External thermistor can be used for better reading.

Light Sensor

• The light sensor returns an integer that ranges from 0 to 750. Zero represents complete darkness.

• Peak sensitivity of light sensor is at 600nm wavelength.

• More exact reading when sun-roof is removed.

LEDs

• There are 8 three-color LEDs on the demo sensor board.

• Each LED can display RGB color ranging from 0-256.

Communication/Networking

• Each client device and the workstation can communicate with themselves and the other devices wirelessly.

• USB interface with the PC is provided.

• Workstation can remain connected to the PC for the processing on the computer itself.

• The Sun SPOT processor board has a 2.4GHz radio with an integrated antenna on the board.

Simulators

• Allow testing of the programs of the desktop

• No need to posses the device during testing or debugging.

Development Steps

• Install JDK, Netbeans, Sun SPOT SDK and Drivers

• Create Sun SPOT project

• Compose your application

• Connect, Compile and deploy application to SPOT

• and you are done!

Application Domain

• Environmental Monitoring

• Security

• Defense

• Bioinformatics and Health

• Transportation management

Conclusion

• Suitable :– Rapid development– Experiment– Education

• Not ready to commercial solution

• Future development– Open source– Get support from sensor providers like

J2ME support mobile phone companies.
