AIR QUALITY OF MONITORING SYSTEM

The system presented in this project 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 is the scale to measure how polluted the air is. Greater air pollution indicates more dangerous air is for human health. The model presented here uses a combination of the ESP32 software and hardware along with a Gas sensors – MQ135, MQ7 and DHT11 sensor which help in detecting gases like NO2, CO, Ammonia, and Sulphide. Further, this research work monitor the Air Quality over an IOT analytics application BLYNK using internet connected with the hardware. It can also integrate the real time data into our mobile phone app. The circuit finally displays the PPM values as well as Air Quality level of gases on an Android application which fetches data from sensor through IoT. The current model is implemented successfully and can be deployed for real system implementations.
