摘要： Various embodiments are directed to a fluid composition sensor device and method of using the same. In various embodiments, the fluid flow composition sensor is configured to receive a volume of fluid, the fluid composition sensor comprising a housing, a removable fluid flow component, an impactor nozzle, a collection media assembly dock element configured to receive a replaceable collection media assembly comprising a collection media configured to receive one or more particles within the volume of fluid, an imaging device configured to capture an image of at least a portion of the one or more particles received by the fluid composition sensor, and a controller configured to determine, based at least in part on the image, at least one particle characteristic of the volume of fluid. The imaging device may be configured to capture the image of one or more particles received by the fluid composition sensor using lensless holography.

摘要： Methods and apparatuses associated with flow sensing devices are provided. An example flow sensing device may include a sensing element disposed at least partially within the housing, and a plurality of channels disposed within the housing defining a flow path configured to convey a flowing media through the flow sensing device, wherein the flow path is disposed proximate the sensing element such that at least a portion of the flowing media makes direct contact with the sensing element.
