POLLEN SENSOR

摘要

An apparatus for identifying airborne particles and a method for identifying airborne particles is described. In one embodiment, the apparatus utilizes an electrode to charge airborne particles and accumulate the charged particles on a collecting plate. In another embodiment, the apparatus utilizes a laser beam to isolate airborne particles on a collecting plate. A CMOS array records an image of the particles on the collecting plate, and a computer executing image recognition software identifies the particles. The apparatus is particularly useful for identifying airborne particles such as pollen, and may also be used to identify other particles present in the air such as dirt, dust, and mold spores.
