Abstract
A particulate matter sensor is provided. The particulate matter sensor includes: an insulating substrate; a first electrode unit, and a plurality of spaced electrodes; a second electrode unit and a heater unit. Wherein each of the spaced electrode includes a sensing unit, wherein the particulate matter is deposited on the sensing unit, and a capacitor unit is configured on the spaced electrode for measuring capacitance. The plurality of spaced electrodes and the rim electrode are electrically connected when particulate matter is deposited, and thereby the capacitance between the first electrode unit and the second electrode unit can be measured.
