Inspiration

Seeing constant news regarding car thefts, accidents related to underage driving made us feel an urge to create a project that provides car security in a very simple yet effective manner. India is a country with a lot of 'unordered' road systems, so large car security systems or even cars with security features become inefficient. So we were inspired to create something small and cheap which can provide luxury car security to the Indian middle classes.

What it does

Parivartan is aimed towards combating car thefts and to avoid underage driving. Using Raspberry Pi and Python, along with high class security features like fingerprint sensors and smart DLs readers, we have made an easy-to-install and extremely secure security feature to help in providing top tier car security to the consumers.​

Using top-notch security features like fingerprint sensors linked with smart DLs and QR codes, we provide an additional effective wall of security and safety. User's car is only started in case the correct DL-fingerprint combination is applied. In case, if the user's smart DL is missing, then we have an option to validate the entry through a QR code (the QR code will be sent to the user beforehand). In this case, the QR code behaves just like the smart DL, and the user will just have to scan their fingerprint and show the QR code in front of the camera module for verification.

Parivartan also uses its Motion Sensor to detect for human presence in a locked car. This is done in case an infant/child/adult is left unattended in a locked car, then he/she might suffer from suffocation and heat stroke. If Parivartan does sense such human presence, then an alert is instantly sent to the user's mobile regarding the same.

So Parivartan provides a luxurious layer of security to a car system through very simple steps and procedures.

How we built it

The road to build Parivartan was a long one. We started off with a basic understanding of what our product has to achieve and then worked our way up, adding more complexities and solutions along the way. It started from being a simple replacement to the usual key-ignition security measure in cars, and then evolved to take on other serious issues along the way. Once decided upon the working of Parivartan, the coding of the system began, which remains the most interesting part of this journey. We learnt in-depth about the process of writing a code for a project and how to find and fix errors.

As once the majority of the coding process was once done over the weekend, we began assembling the hardware to form our product idea into reality. Watching it form in front of ourselves was truly a delight. The parts for the project were ordered online, so getting them was not a major hassle.

Challenges we ran into

From the onset of the making, we ran into technical issues, mainly regarding the flow of work. Being it our first experience in creating something, we were not very efficient in doing the same. Other problems like hardware assembly were easily rectified due to our team having very capable members. However, during the end of the project one problem that we faced was the oversaturation of ideas, we wanted to add so much more but weren’t able to due to time restraints and physical limitations. Parivartan is also very delicate, since it doesn’t have a proper container yet. So locomotion of the project is not optimum yet, because of there being a threat of wires disconnecting.

Accomplishments that we're proud of

The base idea of parivartan was only based on fingerprint and smart dl. At that moment adding a digital driver license and motion sensor to it was a part of our future plan. Seeing a part of this accomplished is a big deal for us. This is our first hackathon as well and being able to create such an innovative project for us 11th graders was a big achievement that we are proud of.

Creation of such a wonderful code was also a great accomplishment of our team, since we all are coding enthusiasts. In the end, anything that allows us to portray our passion and enthusiasm is a golden opportunity, and we saw the same golden opportunity when we plugged in the Parivartan system and ran the code successfully. This whole journey has been a very satisfying one, and that has not been less of an accomplishment.

What we learned

During the course of the making, we learnt about the Raspberry Pi module and in-depth python programming. We learnt the process of converting ideas into reality and to take a set of simple sensors to make a complex and effective security system.

We learnt how to manage teamwork and how to go by our strengths, and also the power of good presentation in the success of a project. It is the combination of creativity and skill, along with a rational outlook that makes these projects come to fruition, and we have gained a good knowledge of the flow of control needed to make such projects.

Lastly, we have learnt that every possible thought the crazy idea is not fictional to the books and imagination, but is a step away from being implemented in the real world. We have come to recognize the fact that anything that can be thought of, can also be done and achieved.We have come to realise the potential of a human being.

What's next for Parivartan : Car Security Simplified

We have some things in mind as a part of our future plan which we plan to include to further refine the project. We plan to expand the uses of motion sensors to solve the purpose of lights being left on as well. We also plan to prevent accidents due to cars slipping on slopes (as the handbrake is not put) by adding locational settings. Our aim also plans to tackle the problem of low vision at night due to strong light beams by using obstacle sensors on roads as well just not during parking. To maximize security, we also plan to bring Iris scanners to use alongside the already working fingerprint scanners. All of these are budding ideas which have their own limitations as well but in future we plan to think more on these lines and make the Genz cars safer.
