Abstract

Covid-19 has had a significant impact on many people's lives. Millions of individuals are infected, and millions of people have died as a result of the disease. The virus infects the respiratory system severely. After the lungs have been inflamed, it is difficult to recover. The virus has since mutated, and the infection rate has increased. Various countries' healthcare systems are collapsing as a result of the increasing number of Covid-19 patients. More Covid-19 virus-related research, including healthcare technologies, are being conducted as a result of this. In this study a low-cost respiratory rate monitoring system is described. The system monitors the patients' breathing by using piezoelectric sensors. The sensors are placed on a chest belt with pre-determined size. As the wearer breaths in and out, the sensors measures the pressure of the chest pressing against it. The values obtained indicate the chest expansion and deflation. An Arduino Uno was utilized to read the signal acquired by the piezo sensors. It sends the data can be viewed on the serial plotter. The respiration rate per minute is calculated in the microcontroller and sent to the smartphone via ESP8266 Wi-Fi module to be displayed on the smartphone using Blynk app. The status of the respiration rate i.e. normal and abnormal are displayed when breathing is in these ranges. This work shows another modality to monitor Covid-19 patients.
