Design, Hardware Implementation of A Domestic Pulse Oximeter Using IOT For COVID – 19 Patient

Abstract

In COVID – 19 eras, research shows that many people died in coronavirus due to shortage of oxygen in the body. Another symptom of COVID is high fever. So, it is very needful to keep track of the Oxygen level and Temperature of the patient. In present market several types of pulse oximeters are present, but none of them is IoT enabled hence one must physically come close to the patient to check the health conditions, this cause infection to spread among the health staff or the family members. COVID-19 is highly infectious disease and can be treated at home, but the patient has to stay in isolation during treatment period. Hence, a simple, easy cost-effective pulse oximeter enabled with IoT based remote monitoring. is proposed, designed, and implemented. This device can measure body temperature, pulse rate and oxygen level (SpO2) of the patient and can show the data remotely. Here minimum number of sensors are used to maintain cost effectivity and operation simplicity of the device. Ability to connect to IoT platform enables this device to monitor oxygen level remotely from smart phone via Blynk IoT platform. Blynk is a hardware connected mobile IoT platform to monitor data remotely and it is free to use. An OLED display is also installed in the device. So, measured data can be visible in both the device and in IoT connected app. A 5V DC USB type micro-B power adaptor needed to power up the device. An alarm indicator is setup when heartbeat is measured by the device. LED is set up inside application page to warned on body temperature rise and fall of oxygen level., thus someone can take necessary steps to prevent casualty of that patient.
