Microcontroller Based Home Automation System With Security
[attachment=16219]
INTRODUCTION
With advancement of technology things are becoming
simpler and easier for us. Automation is the use of control
systems and information technologies to reduce the need for
human work in the production of goods and services. In the
scope of industrialization, automation is a step beyond
mechanization. Whereas mechanization provided human
operators with machinery to assist them with the muscular
requirements of work, automation greatly decreases the need
for human sensory and mental requirements as well.
Automation plays an increasingly important role in the world
economy and in daily experience.
HOME AUTOMATION
Home/office automation is the control of any or all
electrical devices in our home or office, whether we are there
or away. Home/office automation is one of the most exciting
developments in technology for the home that has come along
in decades. There are hundreds of products available today that
allow us control over the devices automatically, either by
remote control; or even by voice command.
III. NEED OF AUTOMATION
Earlier, we looked into the face of future when we talked
about automated devices, which could do anything on
instigation of a controller, but today it has become a reality.
a) An automated device can replace good amount of human
working force, moreover humans are more prone to errors and
in intensive conditions the probability of error increases
whereas, an automated device can work with diligence,
versatility and with almost zero error.
VII. CONCLUSION
An automated home can be a very simple grouping of
controls, or it can be heavily automated where any appliance
that is plugged into electrical power is remotely controlled.
Costs mainly include equipment, components, furniture, and
custom installation.
Ongoing costs include electricity to run the control systems,
maintenance costs for the control and networking systems,
including troubleshooting, and eventual cost of upgrading as
standards change. Increased complexity may also increase
maintenance costs for networked devices.
