Currently, Corona-virus disease (COVID-19), one of the most infectious diseases in the 21st century, is a highly contagious viral infection with a severe impact on global health. It also affected the global economy very badly. This virus threatens human’s life, and it is necessary to design a monitoring device to monitor the patient’s health remotely to avoid the spread of infection to doctors or nurses. In this paper, a wearable device which contains two sensors are used to measure blood oxygenation, body temperature, and heart rate. Then send these readings to the server to analyze them and send warning notifications to the patient’s assistant phone to inform him of whether the oxygen level is low, the heart rate is irregular or the patient's temperature is high to perform a certain procedure to aid the patient.
