Air quality monitor


         In this project, we can monitor the atmospheric gases using MQ 135 gas sensor, which can be used to sense the gases like benzene, alcohol , smoke. We can get these data’s in blynk app from anywhere in the world. NodeMCU ESP8266 is a low cost open source IoT platform. By connecting to the Wifi network, we can get the data’s from sensor.

Proposed system

  • In this project, we are monitoring the atmospheric gases using MQ 135 gas sensor.
