Recent developments in the production of inexpensive indoor air quality monitoring device

The level of pollution has increased with times by lot of factors like the increase in pollution, increased vehicle use, industrialization and urbanization which results in harmful effects on human wellbeing by directly affecting health of population exposed to it. In order to monitor quality of air-based system is purposed. Air quality plays very important role in safety, security, and health of the mankind. In this study, carbon monoxide (CO) and air quality (Qa) were measured using MQ135 and MQ7 sensors, respectively. Measuring air quality is a crucial step in raising awareness among the public about the need to ensure the health of future generations. Based on this, the Government of India has already taken some steps to outlaw motorcycles powered by single- and two-stroke engines, which are comparatively releasing significant levels of pollution. Using IoT platforms like Thingspeak or Cayenne, we are attempting to develop the same system so that we can educate everyone about the damage we are doing to the environment. New Delhi has already been noted as the most polluted city in the world with air quality readings over 300 ppm. The other papers have been fixed by us. We have updated the other publications where the sensor calibration and PPM projection were incorrect.
