INTRODUCTION
• In the current global scenario the
main question in every women
mind is their safety and security.
• The only thought haunting them
is when can they move freely all
around without worrying about
their security.
• With the advancement of
technology it is now feasible to
provide security or self defense in
more than one way.
• With the increasing crime against
women we have decided to post
projects on the safety of women.
• This project on women security
system is made to minimize the
risk of accidents and will reduce
the rate of mishaps.

MOTIVATION
• Due to rapid increase in crime against women we
were highly motivated to think upon this topic.
• Today we live in the world of irony. On one hand
we have advanced a lot in the field of technology
and advancement in general has been
unprecedented level and on the other hand we live
in a world where crimes rates are high mostly
crimes against women have risen to an alarming
level.
• These have motivated us to focus on such a topic.

DESIGN GOAL

for women security system
• This project is conducted to design a potable alert
security system for women. Due the growing
crime against women such alert and security
system needs its existence.
• This project is focuses on the security and alert
system for women so basically it includes all
positive impacts as a women can alert the people
around if she faces any harsh situation.

DESIGN EVOLUTION
• Initially women security system was evolved through mobile apps. In this project the hardware
implementation is done and a physical protocol is made to give women a better alert and security
system.
• Thus, we have proposed a product to minimize the risk of mishaps and alert women which
includes the use of sensors, micro controller, GSM (Global system for mobile communication),
GPS (Global positioning system), buzzer, LCD (Liquid crystal display) and shock generator
circuit.
• Basically, we will be using two types of sensors vibration sensor and heart beat sensor. These
two sensors along with a manual switch will be given as inputs to the micro controller.
• The GPS and GSM modules will act as output and transmit the data to the mobile phone via sms
(short message service) followed by continuous calls.
• A LCD will also be placed that will show the data that is being transmitted through the micro
controller.
• Using these electronic devices, a reliable security system for women can be made. It will not just
act as an alert system by ringing the buzzer and sending messages to the registered contacts but
also comprises of a self defense mechanism.
• When the switch is clicked by the victim or when the threshold values of both the sensors
exceed, the current location of the victim can be tracked by GPS module and micro controller
transmits the signal through GSM, sms is sent followed by simultaneous call for better alert
system. LCD displays the respective message, the buzzer rings and the shock generator circuit
gets activated to make the attacker immobile for few seconds.

EXISTING MODEL
• There are many mobile apps invented in past for women
security which are unreliable and less efficient.
• The existing systems are all wired systems which are
conventional and cannot communicate efficiently.
• The hardware implementation using voice recognition system
and spy camera also has many constraints.
• Lots of apps are developed that can send current location or
make an automatic call to any family member or police station
but its hardware implementation is not yet feasible.

PROPOSED MODEL
• The proposed model mainly emphasis on women safety and to overcomes the
disadvantages in the existing system.
• The transmitter part of the proposed model includes :
• Sensors
– Heartbeat sensor
– Vibration sensor
• Switch
• Power supply unit
• The receiver part of the proposed model includes:
• Gsm
• Gps
• Shock generator circuit
• Buzzer
• Lcd display

STEPS FOR IMPLEMENTATION
• The proposed model mainly emphasis on women safety and to overcomes
the disadvantages in the existing system.
• The transmitter part of the proposed model includes :
• Sensors
• Switch
• These collects the signal from the women and gives it to the
microcontroller.
• After processing, the microcontroller transmits the signal through GSM
using GPS to track the location to the authorized mobile numbers
provided.
• The LCD displays will also show the respective message that is transmitted
followed by a phone call.
• There is also a buzzer present which will ring as soon as the signal is send
that the women is in danger.

Testing, Analysis, and Evaluation
• Power supply circuit for women security system :

OVERALL CIRCUIT DIAGRAM OF WOMEN SECURITY SYSTEM

LIFELONG LEARNING
• While the commencement of the project we
learned the use of proteus and keil software.
These software can be used in military
services, control technology teaching. Keil can
be used further in robotics.
• We learned about the hardware shouldering.
This can be helpful in robotics or any other
hardware projects.

CHALLENGES
• The app could only work when the data connection is on.
• The victim at a sudden moment is not always ready with
the mobile.
• Tracking the location at times is difficult.
• There is no self defense system.
• Since we are using both automated and manual inputs a
major problem arises with the automated sensors.
• We are basically using two sensors: a heartbeat sensor, a
vibration sensor and a voice speech recognizer. The main
constraint arises when the threshold value of both the
sensors exceed and also simultaneously due to some
external force the voice recognizer gets activated which is a
rare case then the buzzer and signal to micro controller can
be stopped by pressing a switch manually.

TEAM CONTRIBUTION
• Sukruti Dash: she being the team leader maintained the required
decorum among the group. She also gathered information about the
customer needs through interviews of technical persons. She did the
tables assigned to her along with some of the student outcomes. Then in
