Abstract

A soot sensor includes a soot sensor including a sensor element and heater element disposed on a first surface of the soot sensor. A soot sensing system may include a soot sensor and circuitry electrically coupled to the sensor and heater elements of the soot sensor. The circuitry is configured to determine an amount of soot accumulated on the soot sensor and to control heating of the heater element in response to the soot accumulation.
