This project aims at providing security for women by detecting Heartbeat rate of a person whenever they face threat. That is the reason to develop this project that can act as a rescue device and protect at the time of danger.

Objective:

After detecting signals, the sensor transmits the output electrical signals to the controller. The Arduino 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 app.

The sensors used in the proposed system are flex sensor, temperature sensor, MEMS accelerometer, sound sensor pulse rate sensor. Each sensor is used to detect signals 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, when 4 sensors out of 5 sensors crosses the threshold limit the buzzer is activated.

Hence the GPS transmits the location to the Arduino and then the Arduino transmits the signal to the wifi. Finally the alert message “I am in danger” along with the latitudinal and longitudinal location is send to the registered contact number.

Introduction:

Day by day the women harassment increases. We can’t change the society totally but we can increase the security of girls by using modern technology. Now-a-days Though there are many apps evolved for women safety via smart phone it is activated only by a touch or one click or shake. It is not possible to have mobile in our hands in all circumstances. In order to overcome this problem we are developing a gadget that works automatically.

That’s the reason to develop this project that can act as a rescue device and protect at the time of danger. The motivation behind this project is an attempt to focus on a security system that is designed merely to serve the purpose of providing security to women so that they never feel helpless while facing such social challenges. An advanced system can be built that can detect the location and health condition of person that will enable us to take action accordingly based on electronic gadgets like GPS receiver, wifi , pulse rate sensor, flex sensor, MEMS accelerometer, body temperature sensor. We can make use of number of sensors to precisely detect the real time situation of the women in critical abusive situations. The heartbeat of a person in such situations is normally higher which helps make decisions to detect the abnormal motion of the women while she is victimized.

Scope:

The project is an attempt made to solve the problems of women safety. The scope of the system is to develop a smart device which can help women in some emergency situations. The main objective of the system is to provide a reliable security system for women when they are alone or feel unsafe. WIFI  and GPS based tracking system is currently used in this project here the GPS module tracks the location of the victim and app module helps to send message Saying “I am in danger” to the pre-registered numbers along with the location of the victim and a buzzer is used that alerts the surrounding people that the particular person is in danger. Apart from other systems our system can send the current location and does not require mobile phone or any software on the help seeker’s side

Proposed system Architecture:

The architecture of proposed system as shown in Fig 1 consists of Arduino controller [5].as a main source and it

receives input signals from the sensors, where thereby the sensors receives the input signals from a human who is in threat or in danger or in abnormal situations. Fig: 1. Architecture of the Proposed System
