Outdoor enclosure for PMS sensor

I'm working on a project that require the measurement of particulate matter. I'm using the PMS3003 sensor:

This sensor obviously requires an air flow to measure the particulate matter, but my problem is that I need to put this sensor in outdoor. I was thinking putting in a plastic enclosure for protecting it from rain, but it will not allow the airflow to enter the sensor, and making a hole in the enclosure will make the rain and humidity enter. Is there a type of enclosure that helps in this issue? or maybe a membrane that blocks water and let the airflow pass?.
