2021-2022 Project (2nd Blog Post)

Data collection with the finger on the sensor allows the Raspberry Pi to detect heartbeat and blood oxygen level through a computer. The information can be sent to the server but needs to be stored.

The first problem I ran into was the complexity of connecting the heart rate sensor to the Raspberry Pi. The second problem was the sensor being too sensitive with the finger touching it directly, so I cut a small piece from a ziplock bag and put it over the sensor.

My dad has also been incredibly helpful with some codes I didn’t understand and having essential materials that are good for this project.
