Abstract

In detecting a particulate matter (PM), which measures a change in capacitance depending on induction of the particulate matter, an apparatus for detecting a particulate matter includes: a power supply unit applying bias voltage for inducing the PM; a detection unit forming a magnetic field by using detected voltage applied from the bias voltage and generating PM resistance by the PM by inducing the PM to the magnetic field; and a measurement unit including a first capacitor and a second capacitor in series and measuring the changed capacitance of the first capacitor and the second capacitor according to a change in PM resistance by connecting any one capacitor to the detection unit in parallel. A method for detecting a particulate matter includes: applying bias voltage; generating PM resistance; and measuring changed capacitance according to a change in PM resistance by using the apparatus.
