Abstract: In one embodiment, a system includes a sensor and an airflow generator coupled to an airflow guide configured to direct airflow from the airflow generator toward and past the sensor. The system includes one or more processors and a non-transitory computer readable storage media embodying instructions coupled to the one or more processors, the one or more processors operable to execute the instructions to acquire data about an operational state of the system, wherein the operational state is related to at least one air contaminant generated by the system; and to control the airflow from the airflow generator based on the data about the operational state of the system.
