In order to design the wearable device, I chose the optical sensor MAX30100 to connect with the smaller Arduino Nano. The purpose of this week is to complete the entire monitoring system used in the Arduino Nano.

Circuit connection diagram:

According to the requirements of figure 1, the product can be seen in Figure 2.

Next, add the header file of the LCD display to the original program and set the output parameters to heart rate, blood oxygen, and temperature. Finally, add the output to the LCD display.

After that, operate the program again. Put your finger on the LED of an optical sensor, the data can be displayed on the LCD screen, iPhone and PC.

Conclusion:

So far, the basic functions of the entire project have been completed. Heart rate and blood oxygen concentration are detected. Wireless transmission of data via Bluetooth has been completed. The next step is to design it as a wearable product. Design all components onto the PCB board. Because of the limitation of time, the wearable product will be completed in the future.
