Abstract - Air is essential for every living thing. Due to urbanization, there is growth in polluting industries, burning of wood, construction waste, substantial loss of forests and vehicles. Air pollution is a serious issue, the main objective of this system is to estimate the quality of air which all living things breathe. MQ9 and MQ135 gas sensors are used to detect the air quality of the environment. Node MCU ESP8266-12e microcontroller is used to convert analog values from these sensors to a digital value in ppm and display it on an LCD screen. The outputs from the sensor will be updated to the cloud through the Wi-Fi module and are stored and monitored using the IoT platform.

Keywords: Node MCU, Gas Sensors, Arduino IDE, Thinger.io
