Abstract:
A rain sensing apparatus for using a reference photo diode is provided to recognize the amount of rain by attaching a rain sensor having the reference photo diode on a windshield of a car. A rain sensing apparatus includes an LED(Light Emitting Diode) light source(35), a photo diode(36), a reference photo diode(39), a micro computer, and an infrared filter(33). The LED light source emits an LED light to a windshield(12). The photo diode corrects the LED light reflected from a rain dropped on the windshield and performs photoelectric conversion. The reference photo diode detects light entered from an outside and performs the photoelectric conversion. The micro computer detects a difference of photoelectric signals corrected through the photo diode and the reference photo diode and determines the amount of the rain. The infrared filter is formed at a slit(44) of a part adjacent to the windshield.
