Week 9 (23/9/2019 - 27/9/2019)

Coding for ESP8266 NodeMCU also needed to send heart rate rate to the IoT. Since ThingSpeak has been selected for the IoT platform, the ThingSpeak library should be included in Arduino IDE. To connect the ESP8266 NodeMCU to ThingSpeak, the username and password of the Internet connection need to be the same so that the data can be transferred. In the coding, channel identification and “write API keys” should be filled so that ThingSpeak could be connected.


Example of ThingSpeak Coding


After edit the code, the heart rate data can be sent to the Thingspeak. The results were give a huge different as the pulse sensor was so sensitive.

Week 10 (30/9/2019 - 4/10/2019)

On 2 Oct 2019, a FYP 2 Briefing had been covering: FYP 2 Exhibition Day (Tips & Tricks) and Submission of Progress Report, Final Report & Technical Paper. Students were able to know the tips and how to present their projects during Exhibition Day. The speaker also brief on Submission of Progress Report, Final Report & Technical Paper. Next, a sketch has been made for this project. Google Sketch Up used to draw the casing of the project. A sketch need to be provided some Braille cell for guidance to the blind people.   Left View of the Project Right View of the Project

Week 15 (4/11/2019 - 8/11/2019)

Task: Updating Chapter 4. This chapter includes the findings explanation and the data analysis. During develop this project, most important things that need to be carried out were the objectives. Result 1: Accuracy of Pulse Sensor Circuit Analysis To determine the accuracy of the pulse detector circuit, an experimental analysis was conducted on the pulse sensor circuit. In patient monitor and pulse sensor, heart rate measuring is compared between the pulse oximeter. Here is the contrast between the pulse oximeter and the pulse sensor for reading the heart rate. Comparison of Heart Beat Accuracy between Pulse Oximeter and Pulse Sensor between Five Students Result 2: Classifier Analysis with Audio Output The purpose of this experiment is to determine whether the heart rate status generated by the earphone using Cytron EasyMP3 Shield is consistent with the current heart status displayed through Serial Monitor on Arduino IDE. This is to ensure that the audio was pr...
