Outdoor air quality sensor

Hi there,

I’m currently using air quality sensor GROVE - AIR QUALITY SENSOR V1.3, from your documentation I understand this sensor is meant to measure indoor air pollution. Can you let me know what is the metrics of the readings which the sensor produces (for example, ppm in dust sensor)? - it is not mentioned in your documentation.

Do you have an sensor which is exclusively to measure outdoor air quality?

Your help is much appreciated.
