The measurement of Blood-Oxygen Saturation, Heart Rate, and Body Temperature are very prominent in monitoring patients. Photoplethysmography(PPG) is an optical method that can be used to measure Heart Rate, Blood-Oxygen Saturation, and many analytic about Cardiovascular Health of a patient by analyzing the waveform. With the COVID-19 pandemic, there is a high demand for a product that can remotely monitor such parameters of a COVID patient. This paper proposes two major design architectures for the product with optimized system implementations by utilizing the ESP32 development environment and cloud computing. In one method it discusses edge computing with the Fast Fourier Transform(FFT) algorithm to extract features from the waveform before transferring to the cloud while the other method transfers raw sensor values to the cloud without any loss of information. This paper especially compares the performance of both system architectures with respect to bandwidth, sampling frequency, and loss of information.
