Sensor device and wiper controller having sensor device |
摘要 |
A sensor device for detecting wetting on a windshield includes a light emission element for emitting a light, a first light reception element for receiving the light in a first light path that includes reflective redirection by the windshield, and a second light reception element for receiving the light in a second light path that does not include reflective redirection by the windshield. The sensor device uses a ratio of the amount of the received light by the first light reception element and the amount of the received light by the second light reception element to determine wetting on the windshield.
