IT IS A DEVICE FOR WOMEN FOR THEY ARE SAFETY USING WIRELESS COMMUNICATION,

3. The main purpose of this project
women safety.
This device act as an emergency device
for women, When she in potential
danger.
When she is in potential danger, then
bring the NFC ring to NFC receiver then
our device recognised she in danger.
 Then our device immediately send
location link through SMS to pre-fed
mobile numbers.
Through that link location is open in the
google map or NAVIC application.
 This concept was devised in the wake
of serious crime against women in India
and to help curb those crimes.

4.  Switch is used to indicate the controller to sent the message.
They used non-rechargeable battery.
GPS and GSM modems are separately used.

5. PROPOSAL:
 We are using NFC(Near Field Communication).
 We are using the Radio Frequency Technology.
 We are using solar panel.
 We are using rechargeable battery.

6.  Solar panel is connected to the battery.
 When the switch is turned ON, the device will start
working.
 If any problems arise to the women, at that time she
should bring the Smart ring closer to the NFC
receiver .
 The smart ring contain a chip as a NFC transmitter.
 As the signal received by the NFC receiver, the
receiver indicate the Arduino Board that NFC data
received.
 Then sim808 starts GPS to tracking the location of
the person.
 After GPS signal is tracked the sim808 starts the
GSM to sent the GPS location through link to
already pre-defined mobile number in Arduino.
 When the user touches the link received in message
it will open in the google map application.
 It will direct the user to the current location with the
help of the Google Map.
 It is sent message for every 20sec.
 When the location changes it will get updated
immediately and shows the current location
continuously.

32-bit Atmel ARM
 Current models consists a USB
interface, 6 analog input pins and 14
digital I/O pins that allows the user to
attach various extension boards.
 The Arduino Uno a board is a
microcontroller based on the ATmega328.
It has 14 digital input/output pins in
which 6 can be used as PWM outputs, a
16 MHz ceramic resonator, an ICSP

10.  This GPRS GSM GPS Shield based on the SIM808
GSM GPRS GPS all-in-one cellular phone module.
You can add location-tracking, voice, text, SMS and
data to your project.
 It operates at constant 3.3v and 5v.
 It works on frequency GSM 850MHZ, EGSM
900MHZ, DCS 1800MHZ and PCS 1900MHZ.
 It combines GPS technology for satellite navigation.
 The SIM 808 is connect the Antenna and GPS,
Antenna for receiving signal and GPS for latitude
longitude time altitude.
 The GPS engine on and gives that is turns on power
to GNSS receiver.
 It has got time latitude longitude altitude and other
data.
 It retrieve the GPS latitude longitude and send its
honest appending to Google Maps at which
allocated mobile number.
 The SIM 808 sends messages to the linked number
with the help of Google Map
 Once we get response from the GPS to print the time
latitude longitude are debug purpose using SIM 808.

11.  Sending SMS first we use 80 plus the sign
the phone number and then we use the
latitude and longitude data and append it to
maps.google.com link and finally it send
SMS as a Google Map link and after a 10
seconds delay
 Finally Google map link is appended to
latitude and longitude data and send as
SMS.
 If we check the mobile for message we can
see the latitude longitude with
maps.google.com link.
 If we touch the link we can see the location
on Google maps location.
 The location exactly shown after, so every
10 seconds we’ll get a message.
 Designed for global market.
 SIM808 is integrated with a high performance
