Abstract
A particulate matter sensor unit including a sensor on one side of an exhaust line and configured to employ an electrostatic induction for generating electric charges by a particulate matter contained in an exhaust gas when the particulate matter passes the sensor. The sensor includes a body portion, an electrode portion formed in a front of the body portion on one side of the front and adjacent to the particulate matter, a heating portion in a rear of the body portion on one side of the rear corresponding to the electrode portion, a power input portion in the rear of the body portion on the other side of the rear and to supply a power to the heating portion, and connection lines to connect the power input portion to the heating portion, which use the supplied power to generate heat for burning and removing the particulate matter.
