Abstract
A sensor for measuring particulate matters is supplied with a bias voltage to form an electric field to increase an accumulated amount of particulate matters at a sensing unit. The sensor includes a sensing unit in which measurement electrodes and ground electrodes are disposed to alternate with one another in a housing fixed to an exhaust pipe. The measurement electrodes are electrically connected to one another, and the ground electrodes are electrically connected to one another. Bias electrodes are disposed between the ground electrodes to supply the bias voltage to the sensing unit. The bias electrodes are electrically connected to one other.
