Miniaturize particulate matter detector and manufacturing method of a filter

Abstract:

In an embodiment, a miniaturize particulate matter detector includes a filter having a plurality of holes, and a concentration detector correspondingly disposed under the filter. The concentration detector has a detect area used for detecting a concentration of at least one miniaturize particulate matter. A manufacturing method of the filter is also provided.
