SENSOR ASSEMBLY

A sensor assembly includes a housing shaped to be mounted to a vehicle. The sensor assembly includes a first nozzle positioned on the housing and below the sensor and is positioned to dispense a fluid in an upward direction to a surface of the sensor. The sensor assembly includes a second nozzle positioned below the sensor, in which the second nozzle is positioned to dispense airflow to the surface of the sensor. The sensor assembly further includes a ram air structure positioned to receive airflow during forward travel of the vehicle and to dispense airflow to the surface of the sensor.
