1.ABSTRACT:
There has been increased interest in the Zigbee standard, in
particular for building automation and industrial controls. The Zigbee
Alliance has identified six application spaces for Zigbee: consumer
electronics, PC and peripherals, residential/light commercial control,
industrial control, building automation and personal healthcare. This article
deals mainly with industrial control and building automation. Increasingly,
companies developing monitoring and control applications in industrial and
commercial building environments are looking to wireless technologies like
Zigbee to save the cost of wiring and installation and also to allow more
flexible deployment of systems.
2.OBJECTIVES:
The prime objective is to select the appropriate wireless network to
collect the data from sensors placed in the industry ,For the emergence of
XBee in building automation and industrial control .

4. METHODOLOGY:
A block diagram which is shown above is divided into two parts
that is transmitter and receiver. The transmitter part is which is in the
industry which can be monitor & control parameters. The basic principle
used in this device is the property of ultrasonic and waves of getting
reflected when medium density charges. The ultrasonic and sound waves
having a frequency range from 40 kHz are generated by an Astable
Multivibrator, having 50% duty cycle. The waves generated are amplified
and transmitted through a transmitting Transducer with the help of a driver
stage.
.
The waves travel ahead and are reflected back when they strike a
moving object. The receiving transducer selects the reflected waves and
further they are processed in receiver section. The receiver section consists
of pre amplifier, buffer, driver and a buzzer, which gives the final output.
The buffer is included to provide unit gain amplification to the received
waves and passes them to Driver. The output is thus amplified to drive the
output stage. The output stage is a buzzer. LED is also included in the output
stage for the convenience.
5. ADVANTAGES & DISADVANTAGES:
 ADVANTAGES:
1.
Building system control that enables integrated and centralized
management of lighting, heating, cooling and security.
2.
Automation control of multiple systems to improve energy
conservation, flexibility and security.
3.
Flexibility that allows reconfiguration of lighting systems to quickly
create adaptable workspaces and extends to allow upgrades of building
infrastructure with minimal effort.
4.
Safety enhanced through a network where integrated data from
multiple access points enables capabilities .
DISADVANTAGES:
1.
In this project usage of relays leads to consume more power.
2.
It increases the cost whereas digital systems reduce the cost of
system.
6.APPLICATIONS:
1.
This project can be implement in Military applications.
2.
Requiring timeliness and critical data passage may include medical
alerts and security systems.
3.
Repetitive low latency data.
7.CONCLUSION:
Wireless communication technologies can often be useful
within building automation & industrial control applications. An advantage of
using Zigbee radio technology in the implementation of measuring and
monitoring systems is represented by flexibility in topology of the sensor
network. This offers the possibility to reorganize very rapidly the systems. Also
the components of the Zigbee mesh networks can operate over extended periods
of time, even years, without changing the original battery. Zigbee is necessary if
you need to use repeating or mesh networking functionality in your system.
Zigbee technology together with other wireless technologies will profoundly
and completely change the aspect of the industrial automation system
