IMPLEMENTATION OF IOT FOR AIR QUALITY SURVEILLANCE

Abstract

This paper aims to implement Internet of Thing (IoT) for surveillance of air quality of the surroundings and environment using a computer or mobile from anywhere. A low cost open source IoT platform, Node MCU has been utilized for the main controlling role. It has been configured in a manner, such that, it receives the measuring signals from various sensors and displays monitored data through Thing Speak cloud in any connected PC or mobile phone. Besides numeric display, the quality levels of the air are also indicated via different colors of LED indicators. The proposed system not only conveys the AQI information in ppm but also monitor the temperature and humidity successfully in different environmental conditions.
