Real time, an iot-based affordable air pollution monitoring for smart home

Abstract

The emergence of the Internet of things (IoT) facilitates us to connect all the devices available at home. Also, we can control and access devices and appliances remotely in real time. This article, by taking the advantages of IoT, proposes an IoT-based affordable air quality monitoring with smart home system that brings controlling and monitoring of devices and appliances, and monitoring of home environment together in real time. The system uses the combination of wireless communication and cloud networking, to remote control various appliances (like fans, TV), also getting a glimpse of air quality. In order to monitor the home environment, we develop a practical information acquisition model, a network for indoor and outdoor air quality monitoring which can be carried anywhere as a portable device. The portable nodes can sense pollutants like CO, CO2, PM 2.5, PM 10 with temperature and humidity and monitor the air quality. The collected data are sent to a cloud service platform like things speak and Firebase for real-time visualization and appropriate forecasting and prediction analytics. Also, a user-friendly Android app and web portal increase the usability of this system. Moreover, when critical conditions occur, an alert is reflected on the android app and on web portal in real time. Also, the system starts sending a warning ring on registered mobile.
