Abstract
A sensor assembly includes a sensor and a cover disposed adjacent to the sensor to protect the sensor. The cover has an inner cover surface and an outer cover surface opposite the inner cover surface. The inner cover surface faces the sensor, and the outer cover surface faces away from the sensor. The cover has a first end wall and a second end wall apart from the first end wall along a first direction. The sensor assembly includes a cleaning system having a wiper movable along the outer cover surface of the cover in the first direction to clean to the outer cover surface. The wiper is at least partly made of a wiper material, and the wiper material includes a hydrophilic material to facilitate removal of water from the outer cover surface of the cover.
