INTRODUCTIONINTRODUCTION
The main intention of this project is to
find the accident spot at any placefind the accident spot at any place
This project contains MEMS , GSM
module and a GPS modem interfaced
to the PIC microcontroller
contd…
Global system for mobiles(GSM)
technology is used to establish
cellular connection
GSMGSM
cellular connection
GSM is a digital cellular
communication system
It is used for transmitting mobile
voice and data services
GPSGPS
GPS(Global Positioning System)
GPS is used to trace the positionGPS is used to trace the position
GPS Receiver gets the location
information from satellites
MEMSMEMS
MEMS(microelectromechanical system) is a technique of combining
electrical and mechanical componentelectrical and mechanical component
together on a chip
The device typically converts measured
mechanical signals into electrical signals
ABSTRACTABSTRACT
MEMS Sensor used to detect abrupt vibration when an accident occurs

FEATURESFEATURES
PIC 16F73 is a 28 pin IC
4 K bytes flash program memory
192 bytes RAM192 bytes RAM
8 bit , 5 channel ADC
22 input / output pins
3 timers/counters
GSM MODEMGSM MODEM
GSM modem is used to send information
collected from GPS module along with other
details to a specific mobile number
GPS MODULEGPS MODULE
GPS module always receives the information
from satellites regarding the position of the
place where the accident occurs.
MEMS CHIPMEMS CHIP
Whenever any accident occurs MEMS chip
detects and sends electrical signal to the
ADC channel of the PIC microcontrollerADC channel of the PIC microcontroller
POWER SUPPLYPOWER SUPPLY
Power supply unit provides regulated
5v power
The power supply circuit consists of a bridge rectifier which is then passed on to the regulator through a
filter circuit
MAX 232MAX 232
MAX 232 is an dual driver / receiver
It is used to convert the TTL logic level to
RS232 logic levels during serial RS232 logic levels during serial
communication if microcontrollers with PC

WORKINGWORKING
Whenever accident occurs MEMS sensor detect and sends electrical signal to the ADC channel of the PIC signal to the ADC channel of the PIC microcontroller
By using GPS , we get particular location where accident occurs,then GSM modem sends message to authorized mobile number
CONTD..CONTD..
The GPS positioning is done in the form of latitude and longitude along with the exact location of the place with the exact location of the place by making Google maps
ADVANTAGESADVANTAGES
The immediate medication will be provided to the accident victims in the remote areasthe remote areas
Mobile number can be changed at any time
DISADVANTAGESDISADVANTAGES
In some places where there is no provision of GSM networks it is difficult for communicationdifficult for communication
APPLICATIONS &APPLICATIONS &
FUTURE SCOPE FUTURE SCOPE
Automotive Security System
This system can be interfaced with Vehicle
Airbag System
This can also be developed by
interconnecting a camera to the controller
module that takes the photograph of the
accident spot that makes tracking easier
CONCLUSIONCONCLUSION
To take immediate action when an accident occurs by alerting the respective people by sending respective people by sending message
