procedure

We divide our project into three main parts:• Android application (transmitter)• Core circuit (microcontroller)• Wireless communication

What is home automation

Advantages of home automation

• Flexibility & Convenience• Security• Cost Saving• Security• Remote Control

project objectives

• Make our home under control• reduce time & effort and make it more secure• give handicapped people ability to serve

themselves by themselves• Eliminate the use of wires and reducing

installation costs by keep the infrastructure of home without any changes

Name Description.

802.11a

Wi-Fi5The 802.11a standard (called Wi-Fi 5) allows higher bandwidth (54 Mbps maximum throughput, 30 Mbps in practice). The 802.11a standard provides 8 radio channels in the 5 GHz frequency band.

802.11b

Wi-FiThe 802.11b standard is currently the most widely used one. It offers a maximum throughput of 11 Mbps (6 Mbps in practice) and a reach of up to 300 meters in an open environment. It uses the 2.4 GHz frequency range, with 3 radio channels available.

802.11g

 

The 802.11g standard offers high bandwidth (54 Mbps maximum throughput, 30 Mbps in practice) on the 2.4 GHz frequency range. The 802.11g standard is backwards-compatible with the 802.11b standard, meaning that devices that support the 802.11g standard can also work with 802.11b.

Ethernet Shield Module

• What is Ethernet 802.11.3

• Ethernet is the most widely-installed local area network (LAN) technology.

• uses coaxial cable or special grades of twisted pair wires.

• Ethernet is also used in wireless LANs. The most commonly installed Ethernet systems are called 10BASE-T and provide transmission speeds up to 10 Mbps.

Ethernet Shield Module

• What is Ethernet Shield Module

Arduino microcontroller

• Arduino is an open-source single-board microcontroller.

• Inexpensive.• Simple, clear programming environment .

XBEE Module

• Programming the XBee 2 Module

Accomplishment• What we did this semester:1. Attended many of the online courses and read several educational

books about the programming of Arduino and Android.2. Read many topics in addition to the data sheet on how to connect

the XBees on the same network for the exchange of data wirelessly.3. In the practical side and despite significant delay in the arrival of the

electronic parts that we needed in our project, we have done the following:

• Transferring of the data between 2 XBees using serial port.• Writing several codes to make sure that we understand the Arduino

programming properly.• Start writing Android code to use Smartphone in the transfer of the

data wirelessly to the Arduino through a router.

Future work

• Continue reading the books, attending learning courses, and expanding Android and Arduino programs.

• Writing a whole Arduino code to receive Data from Smartphone which will be to run lights or move the engine or Receive Sensors Data.

• Finish writing the Android application in high quality.

• Build and connect the electronic parts together.
