Inspiration

As teen drivers ourselves, we know firsthand how stressed parents are when it comes to their children driving for the first time. To alleviate this tension, we created Savus.

What it does

Simply put, we do half of the worrying for you. The Savus device attaches to the dashboard of any car and automatically detects sudden changes in acceleration. In this situations, a notification is sent to emergency contacts connected in the app and first responders to the details of the location, such as time of occurrence and location.

How we built it

We used an ESP 32 feather and a GY 521 accelerometer to detect changes in acceleration in the X, Y, and Z axes. Then, we linearized the vectors to detect a crash threshold depending on the type of vehicle used.

Challenges we ran into

Calculating an appropriate threshold for the acceleration was a challenge at first because we were unable to visualize a crash occurring. To solve this problem, we used a mini RC car to demo a crash on the very small scale and came up with a threshold value of 2 g (where 1 g = 9.8 m/s^2). We can scale this value depending on the inputted vehicle type.

Accomplishments that we're proud of

We are proud that we were able to create a fully-functioning prototype within a span of only a few days. From ideation to completion to finalizing deliverables, the process was long and arduous. We are proud of how far Savus has come.

What we learned

We each learned about things we were not proficient previously - for example, business-oriented members in our group were able to learn more about hardware and building circuits while still being able to hone in on their business skills (and vice versa for technology-inclined people on the team).
