Week 12, FYP2 : Sketch a banner, Troubleshoot a project, Collect the Data

 Update week 12

For the progress in week 12, I need to do a lot of things before the presentation day. First, I sketch a banner in the PowerPoint, where I put all the information regarding my project. It is purposed to make it easier for the assessor and audience to read and understand the concept of our project. Here are the things that needed to place on the banner:

1. Introduction

2. Methodology

3. Results

4. Conclusion

5. Acknowledgement

6. References

Below is the figure of the banner sketch:

Next, I am troubleshooting the circuit board because one of the components, which is the Infrared Temperature sensor, is not functioning correctly. As you can see from the picture below, a temperature value is not pop up on the Arduino serial monitor.  

The error stated is "nan," which means the sensor is not broken or burned, but it has a problem with the code program. Based on my review, the coding was unstable because there was a clash of communication between the 2 libraries of MAX30100 and MLX. In the beginning, I try to change the bus speed of MAX30100 from 400K to 100K, so it will be the same as the MLX bus speed. Unfortunately, the coding was unstable, and only two parameters could be processed and displayed on the websites. 

Furthermore, I'm trying to modify the coding by adding the reset value codes. Its purpose is to reset all the form values to zero initial values. But it still fails to capture the temperature value. 

Finally, I'm running out of time to do this project, and my supervisor advises only focussing on SpO2 and heartbeat reading. Pictures below show the result that the MAX30100 sensor has captured, and it can be seen through the serial monitor on the Arduino IDE software and on the websites.

I made it to run this project and collected the data with help from a UniKL student. I tested this project on healthy people to observe the functionality of the MAX sensor. Thank god the sensor is working perfectly, and the data show the value is stable.

Last but not least, for right now, I'm still working and testing my project because there are still a few things that didn't fulfill the expectation. Till meet next time and thank you.
