A Wireless Body Temperature and Oxygen Saturation Monitoring system based on Android Smartphones

ABSTRACT

Remote health monitoring is one topic that needs a lot of attention due to the rising number of pandemics. Body fever and low blood oxygen saturation level is clear symptom of COVID-19. Different data display and transmission systems can make monitoring vital indicators such as body temperature, pulse oximeter and heart rate. In this research, thermometry and pulse oximetry have been designed and built with an online monitoring system based on Android. The MAX30205 thermometer sensor was utilized in this study to detect body temperature with high precision. Also, the MAX30102 module was used to detect blood oxygen saturation and heart rate with proper accuracy. The sensors were controlled by an ESP32 microcontroller on the TTGO board, and the measured temperature, blood oxygen saturation level and heart rate were transmitted through Bluetooth to Android devices. These three parameters can be assessed long distances using these circuit and application designs in pandemic conditions. The device's performance was tested successfully and compared with the results of a reference thermometer and finger pulse oximeter. © 2022 IEEE.
