SAFEJET

Inspiration

Many Girls used to go to night shift and return to home after work but it is unsafe to travel alone at night time. So, I decided make a safety smart watch for girls with automatic pepper spray and many safety features while being fashionable.

What it does

When we stuck in any dangerous situation. Most of us will loose our presence of mind. In that cases SafeJet helps. When we get frightened or scared our heart Rate increases. SafeJet monitors your pulse rate when it goes beyond 100, SafeJet start to spray pepper spray by that you can defend your opponent and escape from the place. More features of SafeJet given below.

Features of WatchX:

Pulse Rate: It monitors your pulse rate using PPG (photoplethysmography)

Pepper Spray: I have designed a pepper spray. It’s an automatic pepper spray. While you scared your heart beat increases. So, when your pulse rate goes above 100. Pepper spray starts to spray automatically.

Call: I designed a button in watch which makes an emergency call to your contact.

Emergency Sound: Emergency sound helps you to provide sound which helps people to find you and help to you if you are in danger.

Location: We are having GPS location which helps to find your way when you’re lost.

Weather: You can able to see weather of the city

Low Pulse Rate: If your Pulse Rate goes below 35. An automatic call will goes to ambulance with your current location.

Twitter Feed: You will able to see twitter feed of any account

How we built it

Pulse Rate: PPG sensors are based on the fact that light entering the body will scatter in a predictable manner as the blood flow dynamics change, such as with changes in blood pulse rates (heart rate) or with changes in blood volume (cardiac output).

Digital Signal Processor (DSP) – the DSP captures the light refracted from the user of the device and translates those signals into one’s and zero’s that can be calculated into meaningful heart rate data.

Call: While connecting the Bluetooth to watch. We can make calls.

Emergency Sound: By fixing speakers in watch we can make emergency sound

Location: By using GPS in watch we can locate places.

Pepper Spray: While you scared your heart beat increases. So, when your pulse rate goes above 100. Pepper spray starts to spray automatically.

Challenges we ran into

This is my first Hardware Hack I learned many new things.

Accomplishments that we're proud of

Most of the women’s always put their pepper spray in their purse and if they were caught off guard, they wouldn’t be able to access it. I wanted to have a pepper spray product that was easily accessible and ready for instantaneous use, while being fashionable. Even if we wanted to call a person for emergency, we don’t need to take our phone instead we can call using a button in the watch. I was proud that I have made a super safety watch.

What's next for SAFEJET

Now I have just made a simulation of watch which performs the features of the SafeJet. Next, I planned to Build a real model which we can use it in our daily lives.
