IoT Based Pulse Oximeter System

The Pulse Oximeter instrument can be used to measure the Heartbeat and SPO2 of the person by applying IoT based Wi-Fi technology, which can help to monitor oxygen saturation level and also regular check-up to avoid any the critical situation of health. This device is very much useful to monitor the heartbeat and oxygen saturation level of a patient by a doctor from any part of the hospital premises. In the present paper, a proposed system, which consists of MAX30100 heart rate sensor, ESP32 development board with Wi-Fi has been utilized. Here heart rate and SpO2 are measured in real time and displayed in Android smartphones. This proposed system is compared with exiting portable sensor available in the market. The repeatability and accuracy of the result are found succeed.
