Title: SYSTEMS AND METHODS FOR PORTABLE ASHTRAY WITH FINE DUST SENSOR
Abstract:
Methods and apparatus are provided for determining a particulate concentration level with a portable component (12). The method includes outputting one or more control signals, by a processor, to active a motor (80) to generate an airflow stream through a cavity (66) of the portable component (12); determining a concentration level of fine particulate matter in the airflow; determining an air quality level of the airstream through the cavity (66) based on the determined concentration level; and outputting the determined concentration level with a graphical indicator (136) of the air quality level of display on a display (86) associated with the portable component (12).
