IoT based real time low cost home quarantine patient aid system using blynk app

Abstract

Recently, the world has been hit by COVID-19 pandemic. Nearly about every country has been devastated as they lack a proper health infrastructure. India is one such country where overpopulation is the key reason not everyone has access to medical facilities and are therefore forced to home quarantine. IoT is an ingenious technology which opens a new digitised path in terms of data storage and processing in today's medical world to provide the healthcare systems with the best networking techniques. In this present paper, the authors have created a framework of body temperature, oxygen saturation level (SpO2), BPM (heart rate) and air quality sensors based innovative smart disease surveillance system with amalgamation of nodeMCU. The obtained output is displayed on the LCD display and additionally with the aid of IoT-cloud based app (blynk) the doctor can monitor real time health data. Also, a key feature named Report generates and sends the readings in CSV/Excel format. The health parameters of the proposed prototype have a maximum deviation of 1%, is cost-effective, portable, reliable and high functionality as compared to the commercially available one.
