Abstract- Rapid growth of various high-tech tools and
equipments makes our jobs done comfortable and
sophisticated. The mobile phone is the inseparable part of
human lives today. With the help of mobile phones human
can do many works related to their civil life. At today’s
advanced technology the mobile phone have became smart.
With the help of this smart gadget we can make our home
smarter one. Some products are commercially available in
market which allows home appliances controlling through
internet, GSM, Bluetooth, RFID, and Wi-Fi wireless
technologies. The main purpose of this work is to design an
advanced electrical devices monitoring and controlling at
home or offices remotely using android mobile. The
controlling of electrical appliances is done wirelessly
through Android smart phone using the GSM feature present
in it. Here in this project the Android smart phone is used as
a remote control for operating the electrical appliances.
INTRODUCTION
In Home automation systems there are collections
of interconnected devices for controlling various functions
within a house. Mobile devices are ideal in providing a user
interface in a home automation system, due to their
portability and their wide range of capabilities. . Within the
house, the user might not want to go to a central control
panel, or not even to the laptop, but use the phone that is
usually placed in closer proximity to the user. When far from
the house, the user might want to check its current status or
even schedule actions for his return. But it lacks the true
sense of real mobility, security and some limited range of connectivity. We proposed a new technology so that the
ordinary services of the mobile phones can be used to
communicate with and control the home appliances. Here,
the switch board of our regular use is replacing by Android
mobile application which will communicate with ARM
microcontroller and the android based smart phone. The
home appliances monitoring and controlling is done
wirelessly through Android smart phone and also using
PLCC module. Android is a healthy array of connectivity
options, including Wi-Fi, Bluetooth, GSM and wireless data
over a cellular connection. The advantage of controlling
mechanism is the devices controlling and monitoring is
available in two modes one from Mobile Phone and GSM
devices. The important part of this technique is that the
appliances can be controlled using power line carrier
communication module network and produce required
output. Here all the devices which are to be controlled are
connected to the ARM-7 LPC2148 Microcontroller.
II. LITERATURE REVIEW:
There are two other relevant projects to monitor
elderly using sensor networks and integrating home
automation, but they do not explore user interface design [5]
[6].In Mainardi’s work [7], the project is designed for people
with manual dexterity and mobility impairments, but it could
be widely used. The idea is to have a portable touch screen
device with the proposed interface. Another work presented
the use of touch screen devices combined with voice control,
allowing the interaction of people with limitations in their
upper and/or lower limbs, replacing the standard devices (mouse and keyboard) [8]. The voice control systems in the
state of the art are suitable for interactions with menu
screens. Some works present systems based on a hardwaresoftware
co-design that allows speaker-independent speech
recognition at an accuracy rate of 95%, without voice
training [9].Other works present solutions of image
processing for interacting without traditional interaction. A
gesture-based control system was developed to simplify the
home automation interaction to people with mobility
impairments in the Intelligent Sweet Home project
[10].Another solution was developed to replace hand
interaction using head movements and mouth position [11].
Through serial communication and infrared, the system
controls appliances.
III. NEW CHALLENGES
Android is an open source platform. Neither developers nor
handset manufacturers pay royalties or license fees to
develop for the platform. The underlying operating system of
Android is licensed under GNU General Public. The Android
framework is distributed under the Apache Software License
(ASL/Apache2), which allows for the distribution of both
open and closed source derivations of the source code.
Commercial developers (handset manufacturers especially)
can choose to enhance the platform without having to
provide their improvements to the open source community.
Instead, developers can profit from enhancements such as
handset-specific improvements and redistribute their work
under whatever licensing they want. Android application
developers have the ability to distribute their applications under whatever licensing scheme they prefer. Developers
can write open source freeware or traditional licensed
applications for profit and everything in between.
In today’s world every house and building has
properly installed electricity lines. By using the existing AC
power lines as a medium to transfer the information, it
becomes easy to connect the houses with a high speed
network access point without installing new wirings. This
technology has been in wide use since 1950 and was mainly
used by the grid stations to transmit information at high
speed. Now a days this technology is finding wide use in
building/home automation as it avoids the need of extra
wiring. The data collected from different sensors is
transmitted on these power lines thereby also reducing the
maintenance cost of the additional wiring. In some countries
this technology is also used to provide Internet connection.
Intelligent information appliance is the main
direction of development in the appliance control field.
Intelligent appliance network has small amount and low
speed of data transmission using GSM; there are many
appliances in family and it needs more network capacity.
Network Connectivity
It supports wireless communications using:
GSM mobile-phone technology
3G
Edge
802.11 Wi-Fi networks
IV. METHODOLOGY:
We have presented a system that can be
interconnected with the electrical devices and Arm-7
microcontroller using GSM communicating network. The
communication device used for the communication over the
power lines is a MODEM, commonly known as Power Line
MODEM (PLM). It works as both transmitter and receiver,
i.e., it transmits and receives data over the power lines.
The design of a wireless LPG leakage monitoring
system is proposed for home safety. This system detects the
leakage of the LPG and alerts the consumer about the leak,
activating the alarm. The additional advantage of the system
is that it continuously monitors the level of the LPG present
in the cylinder using load sensor and if the gas level reaches
below the threshold limit of gas the information displayed in
the LCD display .The device ensures safety and prevents suffocation and explosion due to gas leakage. This project is
implemented using PIC controller and simulated using keil
software.
In this prototype, gas leakage detection has been
given a highest priority. MQ6 placed in the vicinity of the
Gas cylinder. In the advent of leakage, the resistance of the
sensor decreases increasing its conductivity. Corresponding
pulse is fed to microcontroller and simultaneously switches
on the buzzer. Also a logic high pulse (+5V) is given as an
interrupt to INT0 pin of Microcontroller. LPG gas leakage
found will be displayed on LCD.LCD continuously monitors
the weight of the gas in cylinder and displays.
