 DESCRIPTION:



The Rapid growth of technology and infrastructure has made our lives easier. The advent of technology has also increased the traffic hazards and the road accident take place frequently which causes huge loss of life and property because of the poor emergency facilities. Our project will provide an optimum solution to this draw back. An accelerometer can be used in a car alarm application so that dangerous driving can be detected. It can be used as a crash or rollover detector of the vehicle during and after a crash. With signals from an accelerometer, a severe accident can be recognized. According to this project when a vehicle meets with an accident immediately Vibration sensor will detect the signal or if a car rolls over, and Micro electro mechanical system (MEMS) sensor will detects the signal and sends it to ARM controller. Microcontroller sends the alert message through the GSM MODEM including the location to police control room or a rescue team. So the police can immediately trace the location through the GPS MODEM, after receiving the information. Then after conforming the location necessary action will be taken. If the person meets with a small accident or if there is no serious threat to anyone`s life, then the alert message can be terminated by the driver by a switch provided in order to avoid wasting the valuable time of the medical rescue team. This paper is useful in detecting the accident precisely by means of both vibration sensor and Micro electro Mechanical system (MEMS) or accelerometer. As there is a scope for improvement and as a future implementation we can add a wireless webcam for capturing the images which will help in providing driver`s assistance.
With the advent of science and technology in every walk of life the importance of vehicle safety has increased and the main priority is being given to reduce the alarming time when an accident occur, so that the wounded lives can be attended in lesser time by the rescue team. This paper provides the design which has the advantages of low cost, portability, small size and easy expansibility. The platform of the system is ARM along with MEMS, Vibration sensor, GPS and GSM, interfacing which shortens the alarm time to a large extent and locate the site of accident accurately. This system can overcome the problems of lack of automated system for accident location detection. Consequently, the time for searching the location is reduced and the person can be treated as soon as possible which will save many lives. This system will have broad application prospects as it integrates the positioning systems and the network of medical based services. The accident can be detected by both vibration sensor and MEMS sensor which will give the accurate information. The controller will process the data, as soon as input is received by the controller the alarm is ON and message is sent through the GSM module. The geographical coordinates and the time of the site of the accident is detected by the GPS module. An alternate condition is given by pressing a switch, in order to interrupt the flow of sending the message in case of no casualty; this will help to save time of medical rescue team and unnecessary alarming which creates havoc in such unusual conditions. The accident location automatic detection will help us to provide security to the vehicles and to the lives of the people. The high priority is given to the lives of the people. Hence, this paper provides a feasible solution to traffic hazards and it gives security to vehicle and reduces loss of valuable lives and property.

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.
