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...
