Abstract: Disclosed is sensor system for use with a windshield that defines at least a partially transparent region. The sensor system includes a glare shield and at least one sensor. The glare shield can be positioned adjacent to the windshield to define a sensor cavity therebetween. The at least one sensor can be disposed within the sensor cavity and oriented with a field of view through the transparent region of the windshield. In some examples, a moisture-trapping material is disposed within the sealed sensor cavity and configured to absorb or adsorb moisture to control humidity and reduce condensation within the sealed sensor cavity. In some examples, the glare shield defines an airflow path through the sensor cavity between an airflow inlet and an airflow outlet to reduce or prevent moisture accumulation within the sensor cavity.
