DESCRIPTION:
Now a day’s so many useful technologies are coming out to make our life style more comfort, luxurious and secure. With advancements in technologies now we are able to design more user friendly systems with low cost.
Now a day’s users expecting smart products with more innovation, creativity, user friendly and security, etc. So in this project we are designing a system to control electrical appliances in home or office or industry just by giving a smart touch on image of the respective load and these images are displayed on the tft lcd for more clarity of the picture.  
The major components used in the project are capacitive based touch screen module, tft lcd and atmel based at89s52 8 bit micro controller.
The communication between touch screen module and micro controller is done through uart protocol and we will store the images binary data in micro controller memory and send this data to tft lcd through tft lcd data lines and control lines.
Automation is controlling of light, climate, doors and window shutters and many more which we can control manually in our daily life. In this project we are going to develop an embedded system, which will control all these devices through pc which are soldered on the zigbee transmitting board.
In this project we are using at89s52 microcontroller for monitoring the equipments in the industries. Working procedure of our project is that we have two embedded systems circuit boards one to transmit the commands and the other is used to receive the commands to monitor devices which are connected to our receiving board to whom we are planning to operate.
This project mainly contains two sections among which one section has microcontroller through encoder and zigbee module transmitter. The zigbee transmitter section transmits the address/data bits to the receiver section. This address/data from zigbee receiver is decoded in decoder. The decoder receives serial address and data from that series of encoders that are transmitted by a carrier using an zigbee, the input data codes are decoded and then transferred to the microcontroller and the controller will either turn on/off light and dc fan through relays. 
The system uses a compact circuitry built around flash version of at89s52 microcontroller with a non-volatile memory capable of retaining the password data for over ten years. The user can modify the password. Programs are developed in embedded c.  Isp is used to dump the code into the microcontroller

Tft lcd (thin film transistor liquid crystal display) is a variant of liquid crystal display (lcd) which uses thin-film transistor (tft) technology to improve image qualities such as addressability and contrast. Tft lcd is an active matrix lcd, in contrast to passive matrix lcds or simple, direct-driven lcds with a few segments.
This is very safe and secure and also we can control many loads without getting confused by adding names or images in the application.
