Abstract
Embodiments relate to systems and methods for providing airflow within a particulate matter sensor. A particulate matter sensor may comprise an air duct, a light source configured to pass light through the air duct, a extender connected to the light source configured to dissipate thermal energy generated by the light source, and to generate a updraft of airflow into the air duct, a photodetector located in the air duct, and a computing device coupled to the photodetector. The computing device has a processor and a memory storing instructions which, when executed by the processor, determines a mass concentration of particles in the air duct based on an output of the photodetector.
