Measuring outside air quality

There is no magical sensor able to measure air quality in any circumstance: for each environment, you must select the appropriate sensor. We have already presented in this blog some ways to evaluate inside air quality, in particular to detect stale air because of CO2. We also talked about sensors that you can use to detect toxic or foul smelling gases, used in particular in the industry. Today, we address how to measure the quality of outside air, that is, the air that everyone breathes daily.

All the Yoctopuce sensors have the possibility to automatically apply a correction to the value returned by the sensor. Let's see how it works.
