1. A system, comprising:
a sensor comprising a lens;
an airflow device disposed around the lens, wherein the airflow device comprises an outlet orifice directed at the lens that is configured to provide an airflow around the lens to prevent debris accumulation around the lens and/or remove debris from the lens; and
a wash system configured to direct water through the outlet orifice,
wherein the airflow device includes a tube disposed around the sensor and having a central opening,
wherein the sensor extends through and directly contacts an inner surface of the central opening of the tube,
wherein the tube has a baffle extending across a cross section of the tube to distribute the airflow within the tube to ensure sufficient pressure and velocity of the airflow exiting the outlet orifice and to prevent debris accumulation about the lens and/or remove debris from the lens,
wherein the baffle divides an interior of the tube into two chambers, and
wherein the outlet orifice is in one of the two chambers.
