TLDR
This is a mini IOT based air quality monitoring system that will monitor the air quality over a webserver using the internet. It will monitor and alert users as and when the levels cross a specified limit. The MQ135 gas sensor is used which will give us output in the form of voltage levels and we convert it into PPM (parts per million). Real time PPM values can also be viewed in the Arduino Serial Monitor. The sensor is capable of sensing gases like NH3, NOx, alcohol, Benzene, smoke, CO2 and other harmful gases.via the TL;DR App
