Operation

Operation With No Rainfall Contacting Windshield

1. Infrared light is emitted from the LED in the rain sensor towards the windshield.

2. The emitted infrared light reflects off the windshield.

3. The infrared light reflected off the windshield is received by the photodiode in the rain sensor.

4. When the photodiode receives the light, the microcomputer in the rain sensor calculates the rainfall amount from the reflection rate, and sends a windshield wiper control signal to the front body control module (FBCM).


Operation with Rainfall Contacting Windshield

1. Infrared light is emitted from the LED in the rain sensor towards the windshield.

2. Emitted infrared light goes through the windshield and penetrates the rain drops on the windshield.

3. The infrared light which cannot penetrate is reflected off the windshield and is received by the photodiode in the rain sensor.

4. When the photodiode receives the light, the microcomputer in the rain sensor calculates the rainfall amount from the reflection rate, converts this to an electrical signal and sends a windshield wiper control signal to the front body control module (FBCM).
