Rain sensor

The rain sensor is concealed behind the front windshield. It can adjust the action of the wiper according to the amount of rain falling on the glass, thus greatly reducing the troubles of the driver. The rain sensor does not change the speed of the wiper with a few limited gears, but adjusts the speed of the wiper steplessly. It has a light emitting diode called LED that is responsible for sending far-infrared rays. When the glass surface is dry, the light is reflected almost 100% back, so that the photodiode can receive a lot of reflected light. The more rain on the glass, the less light is reflected back and the faster the wiper moves.
