Principle of Rain Sensor
Wave which is transmitted reflects and reinput
1. Unit of sensing rain is sensing by the LED and
the diode of photo.
2. As infrared ray is emitting from LED, diode of
photo which is reflected by drop of rain is sensing
the quantity of rain.

(Wave drop of rain is contacting, loss
happen by transmitting electronic wave)
3. Unit of sensing rain is correcting itself, so
regardless of transmitting of windshield, this unit
is constantly sensing rain.
4. This unit is sensing the area between the LED and
diode of photo.
Mode of operation
Wiper control system consist of OFF, MIST, LOW,
WASHER, plus AUTO mode, if turn to the position of
AUTO, rain sensor is sensing drop of rain, and then, is
controliing time of operation, speed of operation with
LOW, HIGH.
