Home Automation Over Internet
Hello friends, i am here with another simple but a useful project "Home Automation over internet". Most of the people thought of controlling home appliances and other things like bulbs tubes and switches etc using an IR remote or a wired things running from your computer to your switch board, but what if you are not at home and suddenly you reminded that you have left something on but you are not sure and you can't even go back.. so what can you do? Don't worry friends solution is here. now access your fully automated home from anywhere in the world that the power of internet... ;-)
So talking about the main thing which you can say the backbone of this project is the HOME AUTOMATION SERVER his software helps you to emulate your serial communication over a very famous remote access utility called TELNET. So basically a telnet server is created at your host PC. A screen shot of the working software is shown below.

Figure 2 shows a block diagram of the full system. We have switches and home appliances that are to be controlled. The embedded hardware is then connected to your PC via serial communication running at 9600 8-n-1 configuration. The HA server is running on the PC with any operating system, with PC's IP configured. You can use a DNS server if you want access all over the internet and if you are using it on LAN then you can have a fix IP within that domain. So using the telnet command with the ip address of the server you can connect to the server.
Figure 2: Block Diagram Of the system
Figure 3 and 4 shows the schematic diagram for home automation project as you can see, we are using LEDs to denote bulbs, tubes and Switches.
As per the program, the tubes are connected at P1.0 and P1.1; Bulbs are connected at P1.2, P1.3 and P1.4; and switched are connected at P1.5, P1.6 and P1.7. The LCD (16x2 LCD) is connected at P2; and three switches which are used to read the messages i.e. P3.2 for read message, P3.3 for next message and P3.4 for Previous Message. Because of the lack of RAM we can only support maximum of three messages.

Following are the commands which are used in our project.
COMMAND DESCRIPTION
stat To get the status of all the appliances connected to the controller.
tube To switch ON/OFF the tubes. Selecting any one out of two.
Bulb To switch ON/OFF the bulbs, selecting any one out of the three bulbs.
swch To switch ON/OFF the switches connected to the controller, selecting anyone out of three switches.
msg To leave a message. Maximum of three messages and each containing maximum 28 characters.
