Design of Rain Sensor Based on Optical Principle

Abstract:

An optical rain sensor which can be used in automobile is described in this paper. The sensor is mainly composed of light source, light collimation system and light focusing system. When it rains, the rain sensor detects the rainfall on the automobile’s windshield surface through the light from the transmitter, and the light intensity received by the sensor receiver can be used to control the wiper to work automatically. The structure of the sensor is designed and the corresponding optical simulation is finished. With the optical rain sensor, the wiper device can work automatically and adjust the swing speed with the rainfall. The performance of automatic control of automobile and the driving safety are also improved.
