In today's polluted world where there is primary air pollutants like SPM, CO2, SO2 and NO2 and secondary air pollutant like photochemical smog particularly in big cities it is highly imperative to have such a device which can detect such pollutants so that one can be cautious about it and also can take appropriate proactive measures and I think air patrol is an ideal solution to the underlying issue.

Thank you and Have a great day.
