Abstract
An apparatus for sensing particulate matter in a fluid includes a substrate; and an integrated circuit electrically connected to the substrate, the integrated circuit including a photodetector. The apparatus includes a filter assembly including a particle filter aligned with the photodetector, and a filter housing for the particle filter, the filter housing defining a flow path for fluid through the particle filter. The apparatus includes a light source electrically connected to the substrate and positioned to illuminate the particle filter.
