Abstract: Smart stun wrist band is easily wearable devices interfacing pulse monitors senses and skin conductance senses embedded with electronic devices and can access network connectivity. The internet of things (IOT) deals with the physical objects which enables information exchange. The design and implementation of the proposed model can monitor the victims mind and activate the stun gun that is embedded in the wrist band. The wrist band overpowers their assailants by stunning the victim with a shock. A Bluetooth module is used to transmit the signal from the band to the mobile phone wirelessly. This paper has proposed a method to develop a portable and affordable device to protect and aid women in distress with minimum response time.

I. Introduction: The world has become unsafe place for women, so why not make a better place using technology. we get a head start to ride the biggest wave that is hitting the industry ever since the advent of the access to Internet. The internet of things is basically is a network of physical objects, devices which are embedded with electronics like sensors, software and network connectivity which enables other objects to exchange data. In simpler terms, Internet of things connects devices and vehicles using electronic sensors, and it allows objects to be sensed and controlled remotely across existing network infrastructure. When. IOT. Is augmented with sensors and actuators technology becomes an instance of more general class of cyber physical systems which also encompass technology such as smart grids, smart homes, and intelligent transportation. The ‘‘THINGS” in IOT refers to wide variety of devices such as sensor DNA, which collect data with help of various technology like smart thermostat systems, or dryers using WIFI. II. Design and implementation: The framework can enable officials to manage and monitor the incident remotely. We at Happiest Minds firmly believe that, as we go forward we should leverage technology to envisage a big change and make a difference in how people live, work and innovate. Let’s go invent tomorrow, instead of worrying about tomorrow as “Once technology rolls over you, and you are not part of the steamroller, you become part of the road”. The proposed system consists of two modules: fear sensing system & Android based mobile phone. The first module consists of apulse monitor and a wearable skin conductance sensor [1], whose properties change when a person is in fear or experiences anxiety. As we know pulse rate increases with fear due to the secret ion of adrenaline, by sensing a change in the pulse 81

rate, one can figure out if the person is in danger. Another factor is the skin conductance.

Sincesweat isanelectrolyte [5]anda good conductor ofelectricity theconductance ofthe skin will increase with sweating. A person tends to sweat when in an un favourable situation like this; by detecting small changes in the conductance of the skin an appropriate decision can be taken [3]. Once it is established that the person is in danger, the proposed fear sensing system strobes Android basedmobilephonetosenda messagetopreselected number. Simultaneously a few capacitors in fear sensing system start charging and all ready to discharge into the attacker who makes a physical contact with the victim. However this electrical shock is good enough to in capacitate the attacker for a good few seconds which are crucial for fight or flight and not damage any part of the body.

Working: Stun guns generate a high-voltage, low-amperage electrical charge. When the stungun is pressed against an attacker, the charge passes into the attacker's body. Since it has a fairly high voltage, the charge will pass through heavy clothing and skin. But at this low amperage, the charge is not intense enough to damage the attacker's body unless it is applied for extended periods of time [4]. Using the concept, we plan to incorporate a bank of capacitors which start to charge as soon as they get the control signal from the microcontroller. Data and respond to the data by sending the pre-stored text as well as the current information to the numbers. We’ll be using Android platform. Application can be designed for other mobile operating systems as well. Using the application we are also making the efficient use of the smart phones. Since most of the phones are equipped with a Bluetooth module, the Application running on the phone receives information that the person is in danger via the Bluetooth module interfaced to the microcontroller. Using the GPS in the phone, it traces the location of the attack. It then sends a common SOS text message to all the pre listed numbers along with the location.

Fig2: Communication Flow Diagram Conclusion: This paper has proposed a method to develop a portable and easily wearable device interfacing pulse monitor sensors and skin conductance sensors to sense the fear or anxiety and a bank of capacitors that are read to shock the assailant if they come in close contact.

This information about the attack is sent as messages to emergency number using Bluetooth in smartphones. The proposed system is capable of constantly monitoring the state of the users mind using the data from the skin conductance and pulse monitor sensors. The stun gun helps even the physically weak users over power their assailants by introducing an element of surprise by shocking them though the shock is not lethal. The estimated cost of the device won’t be very high since we make use of available user’s smartphone and a few capacitors and sensors making safety affordable. A few challenges would be to generate sufficient voltage for the capacitors to shock since batteries are used. It is important that we conclude few power management techniques to improve the overall performance of the device. Given the network infrastructure in our country the information about the attack might not reach as soon as it takes place in the adverse network conditions. However this is subjective to the service provider and the geographical location of the attack.
