Question

Hello everyone. I need some advice with regards to air

quality monitoring. In order to calculate the air quality index accurately, to obtain the relevant data, what are the sensors I should buy?
-Ozone
-Particulate Matter
-Nitrogen Dioxide
-Sulfur Dioxide
-Carbon Monoxide
-Volatile Organic Compounds
-Ammonia

Are there sensors that can accurately monitor multiple of these compounds, or do I have to go for individual sensors for each and every component?
Can you suggest me sensors for the above compounds?

Thanks in advance.
