The purpose of this eewiki post is to highlight and build upon some information from my recent video on the Air Quality Kit designed by Amphenol Advanced Sensors.

Dust measurement

Airflow flows from the bottom inlet and then exits through the top of the sensor, be sure to not cover these two holes. 


This sensor can detect water vapor as dust.  Orientate the sensor in a vertical fashion to allow air to flow through the module. 


For dry particles, you can use a vacuum or some type of forced air to remove dust from the sensor.  For substances such as cigarette tar, you may gently use an alcohol swab to remove cigarette tar from the lens.  Wet cleaning is not recommended.
