Air Quality Sensing and Reporting System Using IoT
Rohan Kumar Jha
Abstract
The system presented in this paper is an advanced real time air quality reporting system supported with Internet Of things (IOT) architecture. Degrading air quality has been a matter of concern nowadays and real time monitoring of air quality helps us to keep a check on it.Air Quality Index(AQ I) is the scale to measure how polluted the air is. Greater AQI indicates more dangerous air is for human health. The model presented here uses a combination of the Arduino UNO software and hardware along with a Gas sensors - MQ135, MQ7 and dust sensor GP2Y1010AU0F which help in detecting gases like NO2, CO and PM2.5 while measuring their amount decently. Further, this research work monitor the Air Quality over an IOT analytics platform - ThingSpeak using internet connected with the hardware via the Wi-Fi module ESP8266. It can also integrate the real time data into our mobile phone app which is specifically created for this purpose using Android Studio. The circuit finally displays the PPM values as well as Air Quality level of gases on an Android application which fetches data from ThingS peak. The current model is implemented successfully and can be deployed for real system implementations.
