I. INTRODUCTION
In fast going world women harassment is an
important issue. For that emergency communication
system (ECS) system (typically computer-based)
organized for the primary purpose supporting of one-way
and two-way communication of emergency information
between any victims/individuals to group of members.
Contrary to emergency notification systems, which
generally deliver emergency information in one direction,
emergency communication systems are typically capable
of both initiating and receiving information between
multiple parties. These systems are often made up of
sensors, Microcontroller, IoT device (WIFI shield), GSM.
Therefore, the origination of information can occur from a
variety of sources and locations, from which the system
will disseminate that information to one or more target
audiences.
Physical devices through which all electronic
devices connected to the internet is called the Internet of
Things. The privacy is very high in the Internet of Things.
It is very helpful to people to develop a smart-based
security. The sensors are developed in such a way that
there is a automatic response without any triggering
buttons. This can help people can overcome difficulties
like women security, constructing smart city.
II. EXISTING SYSTEM
2.1 Problem statement:
In Women and children based security system [1]
victim has to press the emergency button, but in
emergency conditions pressing the button is may not be
possible. Using Smart Phone”, the child cannot send its
location by itself. The parent of that child has to send the
message to the child's system to know their location. In
"Mobile Tracking Application for Locating Friends”, a
tracking application software must be installed in the
mobile phone and the friends must be previously
registered in the friends group of application [2]. To track
their friends mobile phones are needed in both sides. In an
Intelligent System based on RFID and GPS Technologies
for Women Safety[3] has some limitations in terms of cost,
signal interferences and also the information access to
invalid and unauthenticated users. The main drawback of
these applications and services is that the initial action has
to be triggered by the victim [4] which often in situation
like these doesn’t happen. So the emphasis is to build a
solution that works autonomously in situations
encountered. This paper presents new method to provide
protection for women or children by ringing the buzzer
and send the messages to the mobile numbers they stored,
with the location where the victim is present.
2.2 Disadvantages of Existing System:
The main drawback of the system is the when we
use this system the messages which carries the location of
the victim will send to only predefined mobile numbers.

To avoid this problem we added the WIFI shield
enabled with GPS module are used. In this this the alert
messages send to the number of devices which previously
connected to the IoT devices and also the body
parameters are given to the connected devices.
III. PROPOSED SYSTEM
In this proposed system the women security is achieved
based on the IoT device which is connected to the number
of mobile phones or systems. In the previous systems we
use the GSM and GPS modules to send the location and the
alert messages to only predefined mobile numbers. In this
system we send the message and the location to all
connected IoT devices. The proposed system consists of
power supply, Pulse rate sensor, Temperature, Flex
sensor, Sound sensor and Accelerometer sensor,
Microcontroller, WIFI shield enabled with GPS, GSM, LCD,
and Buzzer. The information of the victim who is in
tragedy is updated from the sensors. The heart beat rate is
given from the pulse rate sensor, body temperature is
given from the temperature sensor, sound from the victim
is sensed from sound sensor, the body flexibility is from
flex sensor and the movement of body is captured by the
accelerometer sensor. Then this values are checked with
the threshold value which is predefined in the controller
when it reaches that value. Then the microcontroller will
send the information to the GSM and IoT device using
WIFI shield which having the internet connection to the
device and to the connected device or mobile phones and
proper translation of location information by click the
Track On Map option in the IoT device screen. So we can
easily identify the location and the victim present status
when she is normal or abnormal from the body
parameters. It is also very useful for adults and unhealthy
people
.METHODOLOGY
A. Block diagram and working principle
E
Fig 1: Block diagram of proposed system
The principle behind this is to detect body
parameter signals from the corresponding sensors which
are in contact with the women who are in menace
condition and hence after detecting signals, the sensor
transmits the output electrical signals to the controller.
The controller receives the signal from the sensor as an
analog input signal and hence it generates the output
parameters of each sensor and displays it on the LCD
display. The sensors used in the proposed system are
temperature sensor, accelerometer sensor. Each sensor is
used to detect signals [7] of human (women) who is in
abnormal situations. If values of any sensor signal crosses
the threshold limit indicating that the women is in threat
and according to victim condition, crosses the threshold
limit the buzzer is activated. Hence the GPS transmits the
location to the controller and then the microcontroller
transmits the signal to the GSM. Finally the alert message
“I am in danger” along with the latitudinal and
longitudinal location is send to the connected IoT devices.
Thus stimulation of sensor and buzzer traces the location
of victim using WIFI shield enabled with GPS and with the
help of GSM 900A used sends the message of location to
the corresponding mobile phone or system which is
connected to the IoT devices with a 10secs delay.
IV. HARDWARE DESCRIPTION
A.POWER SUPPLY
The power supply section is the important one. It should
deliver constant output regulated power supply for
successful working of the project. A 0-12V/1 mA
transformer is used for this purpose. The primary of this
transformer is connected in to main supply through on/off
switch& fuse for protecting from overload and short
circuit protection. The secondary is connected to the
diodes to convert 12V AC to 12V DC voltage. And filtered
by the capacitors, which is further regulated to +5v, by
using IC 7805. The power supply for the hardware used in
the system are given below,
Microcontroller – 5v Dc
Sensors – 5v Dc
IoT Modem – 12v Dc
LCD – 5v Dc
Buzzer – 1.5 to 12v
B.PULSE RATE SENSOR:
The Pulse rate or Heart Beat sensor is used to measure the
heart beat rate or the pulse, based on optical power
variation as light is scattered or absorbed during its path
through the blood as the heart beat changes.

Fig 2: Heart beat sensor
C.TEMPERATURE SENSOR:
We can measure the body temperature using various
temperature sensors. For instance, LM35 which has series
of precision integrated circuit sensors whose output
voltage is linearly proportional to the Celsius temperature.
It operates linearly +/- 10.0Mv/°C scale factor with 0.5°C
accuracy. In emergency cases body temperature [10]
varies drastically which can trigger module for rescue.
Fig 3: LM35 TEMPERATURE SENSOR PIN DIAGRAM
D.FLEX SENSOR:
This flex sensor is a variable resistor like no other. The
resistance of the flex sensor increases as the body of the
component bends. Sensors like these were used in
the Nintendo Power Glove. They can also be used as door
sensors, robot whisker sensors, or a primary component
in creating sentient stuffed animals.
Fig 4: Flex sensor
E.SOUND SENSOR:
The sound sensor module provides an easy way to detect
sound and is generally used for detecting sound intensity.
This module can be used for security, switch, and
monitoring applications. Its accuracy can be easily
adjusted for the convenience of usage. It uses a
microphone which supplies the input to an amplifier, peak
detector and buffer. When the sensor detects a sound, it
processes an output signal voltage which is sent to a
microcontroller then performs necessary processing.
Fig 5: SOUND DETECTION SENSOR
F.ACCELEROMETER SENSOR
An accelerometer is an electromechanical device that will
measure acceleration forces. These forces may be static,
like the constant force of gravity pulling at your feet, or
they could be dynamic-caused by moving or vibrating the
accelerometer.
In this system we use the triple axis accelerometer sensor
which is used to measure the acceleration produced from
the victim who is in tragedy.
Fig 6: ACCELEROMETER SENSOR
G. MICROCONTROLLER ATMEGA8
The microcontroller unit is used to control all the
activities. Here microcontroller ATMEGA8 will be used.
The ATmega8 provides 8 Kbytes of In-System

Programmable Flash with Read-While-Write capabilities,
512 bytes of EEPROM, 1 Kbyte of SRAM, 23 general
purpose I/O lines, 32 general purpose working registers,
three flexible Timer/Counters with compare modes,
internal and external interrupts, a serial programmable
USART, a byte oriented two wire serial interface, a 6-
channel ADC (eight channels in TQFP and QFN/MLF
packages) with 10-bit accuracy, a programmable
Watchdog Timer with Internal Oscillator, an SPI serial
port, and five software selectable power saving modes.

H. WIFI SHIELD (ESP8266)
In this system WIFI shield provides the internet
connection to the device. It also having the GPS itself.
ESP8266 is a low cost Wi-Fi microcontroller chip that has
the ability to empower IoT and helps the exchange of
information among various connected objects. ESP8266
consists of networkable microcontroller modules, and
with this low cost chip, IoT is booming. The ESP8266 Wi-
Fi Module is a self-contained SOC (silicon on chip) with
integrated TCP/IP protocol stack that can give any
microcontroller access to a Wi-Fi network. Each ESP8266
module comes pre-programmed with an AT command set
firmware, which can be hooked up to the Arduino to get as
much Wi-Fi-ability as a Wi-Fi Shield offers. The ESP8266
module is an extremely cost effective board with a huge,
and ever growing, community.

I.GSM module
Global System for Mobile communications (GSM:
originally from Group Special Mobile) is the most popular
standard for mobile phones in the world. In this project
GSM used to send the alert messages to the IoT connected
mobile phone and the devices. GSM/GPRS Modem-RS232
is built with Dual Band GSM/GPRS engine- SIM900A,
works on frequencies 900/ 1800MHz. The Modem is
coming with RS232 interface, which allows you connect
PC as well as microcontroller with RS232 Chip (MAX232).
The baud rate is configurable from 9600-115200 through
AT command. The GSM/GPRS Modem is having internal
TCP/IP stack to enable you to connect with internet via
GPRS. It is suitable for SMS, Voice as well as DATA transfer
application in M2M interface.
J. LCD AND BUZZER
The LCD shows the location and the messages on the
display. Buzzer will alarmed when the situation is become
abnormal.
V. WORKING OF PROPOSED SYSTEM
This is the system setup of this module. It consists of
Power supply, microcontroller, pulse rate sensor,
temperature sensor, flex sensor, accelerometer sensor,
sound sensor and the WiFi shield enabled with GPS, LCD
and Buzzer. In this system power supply is turned on then
the sensors will be sensed the information like heart beat
rate, temperature, flexibility, gesture and sound from the
victim. These values are checked to the threshold values
which is predefined in the microcontroller. The values are
not exceeding the threshold value then the output status
will show as Normal. If any one of the value is to be exceed
then the status will turned into Abnormal. Then the
buzzer will be alarmed and the process will be shown in
the LCD display. For that abnormal alert the
microcontroller will be send the information to the WiFi
shield which is enabled with GPS. Then the WiFi shield
send the information to the IoT devices. On the IoT screen
Track Google Map option will show, if we click it the
location will be traced. So in this system we can identify
the location with the body parameters. It also used for
adults and unhealthy people.

VII. CONCLUSION
This paper is all about the existing applications for women
security and comes out with an innovative idea for
security and protection for women and more research is
possible with introducing smart technology where people
and objects form a network. This will help to solve them
technologically with compact equipment and ideas. Using
screaming alarms and also alerting the emergency
contacts which is connected to the IoT device, by sending
the messages with the location is helpful for women’s
security. In this system victim’s body parameter like heart
beat rate, temperature, flexibility, gesture and the sound
are given to the IoT devices. If any abnormal situation
occur this values are shown in the IoT device and the
status of the victim shown. From that we can easily
identified the location using Track on Google map option
on the IoT output. This system can overcome the fear that
frights every woman in the country about her safety and
security. We can identify the health condition of the adults
like temperature, heart beat rate and if they faint due to
any health issue we can easily identify from our place and
ensure that they are in normal or in abnormal situation
using this project. And we can easily track them and
inform to emergency services.
