This document summarizes a project done by a group of 4 students from Sathyabama Institute of Science and Technology. The project is an anti-molestation device that uses IoT technology to send alerts with the victim's location to their guardian when a button is pressed. It lists the group members and their roles. It then describes the motivation for creating such a device due to increasing crimes against women and children. It provides details about the components used, including a NodeMCU microcontroller, GPS module, and push button. It also includes a block diagram, explanations of the technologies used, and a SWOT analysis.

3. ANTI-MOLESTATION DEVICE
Now-a-days, the public, mostly women and children
are facing much harassments in the society. The
unlawful activities against ladies and children have
been increasing significantly, and regularly we find
out about eve-teasing, sexual assault cases, and
attempt to molest or even killing after rape in public
places or open areas. Also, many cases has gone
unwarranted due to short pieces of evidence. In
India, the current statistics of sexual assaults and
various unlawful activities are proliferating. To
acknowledge these problems, we have designed an
IoT (Internet of Things)- based embedded device
that is able to communicate with the guardian of the
victim by sending alert message with the victim’s
present location to them, via GPS (Global
Positioning Sysem), on demand.
• It can send alerts with the
current location.
• It can be made working by
pressing a single button.
• The device is both cost and
power-efficient.
• The device overcome burst-
transmission phenomenon.

6. GPS Neo 6M
Types:-
i) GY-GPS6MV2 **
ii) GY-GPS6MV3
Features:-
1) A complete GPS module with an active antenna integrated, and a built-in EEPROM to save configuration parameter data.
2) Built-in 25 x 25 x 4mm ceramic active antenna provides strong satellite search capability.
3) Equipped with power and signal indicator lights and data backup battery.
4) Power supply: 3-5V; Default baud rate: 9600bps.
5) Interface: RS232 TTL
NodeMCU
NodeMCU is an open source platform based on ESP8266 which can connect objects and let data transfer using the Wi-Fi protocol. In
addition, by providing some of the most important features of microcontrollers such as GPIO, PWM, ADC, and etc, it can solve many of
the project’s needs alone.
Features:-
 Easy to use.
 Programmability with Arduino IDE or IUA languages.
 Available as an access point or station.
 practicable in Event-driven API applications.
 Having an internal antenna.
 Containing 13 GPIO pins, 10 PWM channels, I2C, SPI, ADC, UART, and 1-Wire.
Types:-
a) version 0.9 :- ESP-12 **
MAJOR COMPONENTS

7. Technologies used
G.P.S
The Global Positioning System (GPS) is a satellite-based navigation system made up of at least 24 satellites. GPS satellites circle the Earth twice a day in
a precise orbit. Each satellite transmits a unique signal and orbital parameters that allow GPS devices to decode and compute the precise location of the
satellite. GPS receivers use this information and trilateration technique(method of surveying in which the lengths of the sides of a triangle are measured,
usually by electronic means, and, from this information, angles are computed) to calculate a user's exact location. Essentially, the GPS receiver measures
the distance to each satellite by the amount of time it takes to receive a transmitted signal. With distance measurements from a few more satellites, the
receiver can determine a user's position and display it.
To calculate user’s 2-D position (latitude and longitude) and track its movement, a GPS receiver must be locked on to
the signal of at least 3 satellites. With 4 or more satellites in view, the receiver can determine user’s 3-D position (latitude, longitude and altitude).
Generally, a GPS receiver will track/lock 8 or more satellites, but that depends on the time of day and where the user is on the earth.
Once user’s position has been determined, the GPS unit can calculate other information as well, such as Speed, Bearing, Track, Trip distance and
Distance to the destination.
GPS satellites transmit at least 2 low-power radio signals. The signals travel by line of sight, meaning they will pass
through clouds, glass and plastic but will not go through most solid objects, such as buildings and mountains. However, modern receivers are more
sensitive and can usually track through houses.
A GPS signal contains 3 different types of information:
• Pseudorandom code is an I.D. code that identifies which satellite is transmitting information. You can see which satellites you are getting signals
from on your device's satellite page.
• Ephemeris data is needed to determine a satellite's position and gives important information about the health of a satellite, current date and time.
• Almanac data tells the GPS receiver where each GPS satellite should be at any time throughout the day and shows the orbital information for that
satellite and every other satellite in the system.

SWOT ANALYSIS

9. In this ppt, we have illustrated our device, namely, “Anti Molestation Device”, an IoT-
based safety device. This safety device aims to help women and children from being
harassed in any situation. The device can directly inform law enforcement agencies to
take legal actions against the culprits. Also, the device can send the victim’s current
position to the nearest police station to rescue the victim.
The device is so much user-friendly, and people of all levels can use it without any
hassle at a low cost. Even though we have built a sophisticated system, we still have
some limitations finding the victim’s actual location. Victim’s location can be shared
from the position where he/she presses the button. We are trying to overcome this issue
as soon as possible. Moreover, we will also give our product an aesthetic look so that we
can take it to the mass production level quickly.
