This project shows a simple way to create your own healthcare system.
The system uses an ADC in order to acquire the data coming from a pulse sensor.
The hardest part of the project has been plot in a chart the heart pulse in real time, to do that I decide to try the DevExpress UWP chart component discovering that it's pretty cool!

The Pulse Sensor
I used the following component, it's very funny and it's not an expensive device, for more details please visit this link.
The schematic is very simple and this is my homemade healthcare system:
Software
Software is divided into most two task:
- Data Capturing
Captures data arriving from Pulse Sensor via ADC chip and converts into equivalent pulse.
- Charting
Once the data is captured, it will be plotted to DevExpress UWP chart.
The real time chart is below shown:
It is not feasible to show and explain code here. Please look out my GitHub repository to understand code.
Let's see in action:
Pulse Sensor Fritzing Schema
The 2 LEDs indicate when the GPIO is ready (gpio 4) and the second one when the SPI is ready (gpio 5) to comunicate with the ADC.
The Pulse sensor is connected to the first pin of the ADC.
