Design and Development of Pulse Oximeter Using Internet of Things

With the recent Covid-19 pandemic put break, people are becoming more conscious on checking their SpO2 (Percentage of Oxygen in our blood) and heart rate levels. The pulse oximeter is a widely used clinical instrument for performing effortless testing via a non-intrusive method. The proposed system is a smart device that has been used to monitor the health vitals and monitoring these vitals can help us to track the SpO2 and heart rate. The proposed device comprises of simple components such as a MAX30100 pulse oximeter sensor and an ESP8266 Node MCU. This device can be connected to Blynk App to monitor the regularly updated data through the web by connecting to a Wi-Fi. In addition to this, the SpO2 percentage and heart rate can also be observed on the OLED Display. The proposed system can assist in detecting the health abnormalities like pneumonia, asthma, and many other respiratory diseases.
