摘要：A particulate matter sensor is provided. The particulate matter sensor includesa particulate matter detection unit that has first and second electrodes separatelydisposed on a substrate and configured to generate capacitance to correspond to aquantity of a particulate matter accumulated between the first and second electrodes. Asignal generator is configured to generate a frequency signal that determines a resonantfrequency by the capacitance. A detection result processor is configured to detect asignal magnitude of a predetermined reference frequency in the frequency signal anddistinguishes an exhaust level of the particulate matter based on a change of the signalmagnitude.
