Jul 9, 2024. •. … Web9 aug. 2024 · The values displayed in the serial monitor are NOT ‘ppm’ level of chemical concentration or anything like that. It is mere measure of voltage level from the sensor; Arduino interprets the value from 0 to 1023. So we can say, higher the chemical concentration, higher the values get displayed. Program:
WebAir Quality Index. The Air Quality Index (AQI) is used for reporting daily air quality. It tells you how clean or polluted your air is, and what associated health effects might be a concern for you. The AQI focuses on health effects you may experience within a few hours or days after breathing polluted air. EPA calculates the AQI for five major ...
