Abstract
A particulate matter sensing device includes a screening component, a charging component, and a collecting and sensing component. The screening component separates a plurality of particulate matters from the air by inertial impaction. The charging component is used to produce a plurality of ions to combine with the particulate matters separated by the screening component, making each of the particulate matters separated by the screening component having a first electricity. The collecting and sensing component includes a collecting unit and a sensing unit electrically connected to the collecting unit, to detect the amount of charges of the particulate matters that reach the collecting unit.
