FEATURES Ô
Ô
Ô Ô
This project design makes use of 8051 micro controllers for interfacing to various hardware interfaces. To control the electrical loads from the PC end an AT Keyboard is being used. Control any home appliance or in any industrial type area. Based on Embedded systems.
REQUIREMENTS HARDWARE USED : Ô Serial communication used for downloading the hex code. Ô Serial interfacing with PC. Ô Relay interface. SOFTWARES USED 4 Ô A Cross compiler for compiling and linking the code written for 8051. Ô Serial communication software for downloading code to 8051. Ô Operating System: Windows 2000. Ô Application program development in Embedded C.
MAJOR COMPONENTS Ô Ô Ô
8-bit Microcontroller 8051 (AT89C51) MAX 232 Relay Circuit

APPLICATIONS Hotel power management Ô Street light management Ô Home automation Ô High voltage grid control Ô Industrial automation Ô Electro,hydrolic and pneumatic valve control Ô Robotic control Ô
ADVANTAGES Ô
Ô
Ô
rThe 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. m r Once developed and put to work properly then no further maintenance is required. ! "# r The project is totally machine independent .Not any special packages or hardware is required
SCOPE FOR EXTENSION Ô Ô
Ô
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 for enabling/disabling the electrical devices
CONCLUSION Ô
Ô
Ô
Ô
Ô
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
