Pneumonia and COVID-19 are the most infected infectious diseases that deteriorate health of all range of people. If the early treatment is not provided, it may lead to severe heart disease and eventually to mortality. Therefore, continuous heart rate (HR), as well as blood oxygen saturation (SpO2) monitoring can help to detect abnormalities early. As a result, this paper presents a combination of portable continuous SpO2 and HR monitor which focuses on the improvement of internal design and graphical user interface of the mobile application. In this system, MAX30100, a photoplethysmography (PPG) sensor, was used to measure SpO2 and HR. Then, the signal was transmitted to Arduino Nano as the master microcontroller to process all acquired data from the sensor. The device was integrated with Android-based mobile application through Bluetooth communication, for displaying the result of the measured real-time parameters continuously and for battery status indication. Quantitative measurements showed that the precision of the circuit system implemented for HR and SpO2 were 99.16% and 99.06%, respectively. This system would improve the working efficiency and life efficiency of the healthcare provider and public.
