Development of Blood Oxygen Level, Heart Rate And Temperature Monitoring System by Using ESP32

Telehealth plays an even greater role in global healthcare delivery today. Ever since the pandemic strikes the world, the use of healthcare monitoring systems has a massive boost significantly. This paper aims to develop a prototype of a health monitoring device that can be put at a patient home to replace traditional physical checkups at the hospital by using MAX30102 PPG module and Infrared temperature sensor with the objective to derive PPG signal into basic health parameters such as heart rate and oxygen saturation from the patient through MAX30102 and to test the accuracy of those parameters with hospital patient monitor. The experiment is done by comparing each parameter for 30 seconds in both devices using index fingers coming from 13 participants. From the results obtained, although heart rate suffers motion artefact compared to the oxygen saturation, each accuracy is still excellent with 89.2 and 97.6 percent. In conclusion, MAX30102 PPG and ECG module can get initial health reading through the PPG signal and solve the problems mentioned.
