Patent attributes
A device and a method for detecting fluid particle characteristics. The device comprises a fluid composition sensor configured to receive a volume of fluid and a controller. The fluid composition sensor comprises a collection media configured to receive one or more particles of a plurality of particles within the fluid; and an imaging device configured to capture an image of one or more particles of the plurality of particles received by the collection media. The controller is configured to determine a particle impaction depth of each of the one or more particles of the plurality of particles within the collection media; and, based at least in part on the particle impaction depth of each of the one or more particles of the plurality of particles, determine a particulate matter mass concentration within the volume of fluid.
