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. 一种用于感测流体中的颗粒物的装置；以及电连接至基板的集成电路，该集成电路包括光电检测器。该装置包括：过滤器组件，其包括与光电检测器对准的颗粒过滤器；以及用于颗粒过滤器的过滤器壳体，该过滤器壳体限定用于流体通过颗粒过滤器的流动路径。该装置包括光源，该光源电连接至基板并且被定位以照射颗粒过滤器。
