Smart Indoor Weather Monitoring Framework using IoT Devices and Cloud Computing

Abstract

Environmental factors heavily influence human health. The parameters for the same and their monitoring, both in real time and long term, are of significant importance. The authors of the paper have carefully chosen the parameters and used various sensors to measure them. A group of such low-cost sensors has been networked through a Wi-Fi based microcontroller, the data of which was uploaded on a cloud server for easy accessibility and analysis. The cloud server ensures that the system and the real time stats can be accessed on an android-based smartphone application. What makes this system novel is the parameter selection, thorough monitoring and use of single analog pin of Node MCU microcontroller to multiplex two sensors using diodes.
