4. INTRODUCTION
 To expand Arduino's capabilities by adding an 802.15.4 wireless module(XBee
module)in order to expose its functionality as a Web of Things node.
 To make a heterogeneous network interoperate.
 The implementation of a network stack for the 4 most representativehardware
platforms, as used by the relevant research community(Arduino, SunSPOT,
TelosB, iSense), in the form of a software library, named mkSense,
which enables their intercommunication.

5. MOTIVATION AND MAIN GOAL
Check the
presence
of persons
in a room
Detect
weather a
man is on
the desk or
foot
Controlling
the lights
of the
room
Sensing the
light levels
in the room

7. Arduino:
 Arduino with XBee module for controlling custom
electric circuits (HVAC, lighting).
 Arduinos for physically controlling the lights via added
relays, and for the proximity sensors used in each desk to
determine the presence of a sitting person.
 Arduino hardware is programmed using a Wiring [3]
based language, similar to C++ with some simplifications.

8. SunSPOT:
 It has great computational power.
 It is for decision making and manually controlling
the lights.
 SunSPOT was implemented in Java J2ME

9. iSense:
 Limited power consumption.
 iSense modules because of their easy to use PIR sensor.
TelosB:
 Limited power consumption.
 It helps to communicate between SunSPOT and iSense.
 TelosB motes were running the TinyOS version2.1.0[20]

10. XBee:
 IEEE 802.15.4[12]compliant module.
 With the help of this Arduino can operate as a Smart
Object and expose its functionality in the Web of Things.

14. PROPOSED NETWORK
The main services provided by yhis interface are:
• Registration: Smart Objects register by providing their Mac-Address.
• Data collection: the Controller directly requests for specific data from the sensors
in the network.
• Service request: the Controller requests to be notified when special events occur
on the network,
for example temperature outreached a specified threshold.
• Action request: the Controller orders the devices toper- form some kind of action

17. CONCLUSION
In this paper, how to expand the Arduino's capabilities by adding an 802.15. 4 compliant
module had been described in order to use it as a Web of Things node.
 The process of using it in order to build a platform-agnostic heterogeneous wireless
sensor network.
 All of the necessary steps have been described to make a heterogeneous network
interoperate and the implementation of a network stack.
 In addition, the design and implementation of software library have been described
which can be used for building “intelligent software” for the Web of Things.
 To demonstrate the applicability of this platform two representative has been presented,
use cases scenarios that illustrate how this infrastructure can be used.
