Inspiration:

We got inspired by the importance of health care, and how monitoring certain health factors can be useful.

What it does:

Our glove life analyzer reads heart rate vitals and oxygen levels, and displays them to a dashboard. It also allows zen to use the big display to see all his data and be able to compare it to the average healthy values of a 22 year old (assuming zen is 22 years old!!). The design also includes a proposed hardware design which would allow the user to view their vitals on an OLED display on the back of their hand.

How we built it

Our analyzer focuses on hardware for receiving or obtaining the information, while it uses software to display and compare the results obtained. This was done by using electrical scraps Zen found in their backpack. He came upon an oximeter, raspberry Pi Pico, a breadboard and come connecting wires, as well as some old pair of gloves and glue.

The pulse oximeter sensor once touched will read heart rate vitals as well as blood oxygen levels. The oximeter will be placed on a smaller board (smallest size, as close to a finger width), it will be connected to the main board through the use of longer wires. The main board will be placed on the outer side the hand and the little board (with oximeter) will be at the index finger. This will be implemented as a glove design. The pi will have to be connected to a power supply such as a power bank.

First iteration is designed to have an OLED display like the prototype, later iterations will have a touch screen.

Challenges we ran into

We came across the OLED information protocol complications with the Arduino interface and drivers of the display. To ease this in the future we would choose an OLED with the I2C protocol.

We came across the sensor malfunction, we tried to debug it, serial monitor wasn't showing any values for the oximeter readings and confirmed that the issue wasn't in the code or the wiring. solution was to obtained a new sensor.

Another challenge we face was connecting the raspberry pi to the display, which will be later address and improved on in future iterations.

Accomplishments that we're proud of

We came together and were able to complete the big milestones. Zen was able to use the interface and made sure his health was good. the display/ dashboard appearance is really good. And we are able to obtain actual values so its nice to see the project come to life.

What we learned

We definitely learned a lot from each other, and how important hardware and software go together. Also time management and having someone taking lead for specific parts was useful to be able to get far in the project.

Additionally we learned the importance of ensuring compatibility when selecting and purchasing hardware components.
