ADVANTAGES

User FriendlyThe project has simple and efficient

interface so that a person having elementary knowledge

about computers and only the introductory knowledge

about the system can use it. Easy Handling Once developed and put to work

properly then no further maintenance is required.

Machine Independent The project is totally machine

independent .Not any special packages or hardware is

required

SCOPE FOR EXTENSION

This project can be made wireless also.

Transmitter and receiver can be used with sensors

attached at the hardware box and also at the application

devices so as to make the system wireless.

We can also use mobile phone & internet connection forenabling/disabling the electrical devices

CONCLUSION

The control of different devices in the house interfaced to the micro

controller through PC which is serially interfaced to the micro

controller.

To control the electrical loads from the PC end an AT Keyboard is

being used. Different key presses are used to control various electrical loads fan,

bulb etc.

As soon as we press a key on the keyboard, it generates a signal, and

that signal is received by the micro controller via serial interface RS

232 cable. Hence a single key press on the keyboard is sufficient for controlling

the any domestic appliances
