Design and Implementation of Heartbeat Rate and SpO2 Detector by Using IoT for Patients

In this modern days, development of smart healthcare system is an emerging area of research on the Internet of Thing (IoT). The majority of the individuals who are living in provincial territories are not able to get medical services because of the absence of specialists, emergency and private clinics. Likewise, notwithstanding a little medical issue, the individuals get wavered to get counsel from a specialist due to travel, cost, and time. The heart is the most vital organ in the human body, and the heartbeat rate is an essential aspect of human metabolism. Pulse oximetry is the non-invasive measurement of the oxygen saturation (SpO2) in the heart. However, most of the available heart rate measurement tools are rather expensive and only available in hospitals, and accurate measurement of SpO2 in a rural area may not be possible immediately to measure the level of oxygen level in the human body. In this proposed system, Beer's Law used to implement the Heart Beat Rate, and SpO2 detector used to measure SpO2, heartbeat rate and temperature range. Two different light wavelengths (Red Led and Infrared Led) are used to measure the actual difference in the absorption spectra between HbO2 and Hb. The SpO2 probe placed on the person's finger and the other end with a micro controller to calculate the number of pulses and the amount of the SpO2 present on their body. The measurement range of the SpO2, Heart Beat Rate and Temperature are viewed via OP APP (Outpatient Android Application) and the same is viewed by the doctor in the other end through the cloud. Besides, the interaction will be done between the clinician and patient through video conference in the same OP APP.
