IOT based Heartbeat and Oxygen level Monitoring System

Electronics and telecommunication

A pulse oximeter is used to measure the oxygen level of a person, which is shows how much proportion of the oxygen carrying molecules in the blood are actually carrying oxygen. The saturation point oxygen level is very important to monitor while a patient is at risk for the further process of medication, as a result of the worldwide transmission of serve COVID -19 has evolved into an unprecedented pendamic. currently with unavavailabity of pharmaceutical treatments and low vaccination rates, this novel coronavirus results in a great impact on public health, society and global economy which are likely to last for many years. Internet of things platform is preferred to be utilized to achieve this goal due to its ubiquitous sensing ability and seamless connectivity. IOT technology is changing our lives through smart healthcare or smart city or smart home which aims to build a more convenient and intelligent community. In our system, we are going to measure the saturation point oxygen level as well as pulse rate would be stored in system and it will be available to user side. To monitor person oxygen and heart rate using pulse oximeter. The pulse oximeter is designed using infrared and visible light detection from light that passes through person finger from an emitter. The absorption will tell when blood is moving through the finger and show the results of oxygen and pulses rate. The output of this analog circuit will be connecting to nodeMCU which compute the heart rate and oxygen level from these rates. The values will upload and display on application as well as on LCD.
