摘要：
A particulate matter (PM) sensor includes an embedded self-calibrator. The PM sensor is to be installed in an exhaust corridor of an internal combustion engine. The PM sensor can self-calibrate by imposing a known potential across a protective housing in which the conductive probe is suspended. An image charge that is imposed upon the conductive probe is fed back and correlated to generate an updated calibration for the PM sensor.
