Nowadays, usage of vehicles for transportation is greatly enhanced so it becomes extremely essential to enhance the facility of safety in vehicle cars. In this paper, we introduced system which automatically senses the moisture and switches on and turns off when it rains. Automatic rain sensing automobile car wiper system is automatic as well as smart. Once the rain droplets fall on the system, the sensor senses the intensity and the wiper is actived. The increased speed of movement of rotation depicts the increased rainfall. There is no need of human intervention for wiper control. The system employs an Arduino UNO, rainfall sensor, LCD screen, and a servo motor. The rain sensor identifies rain droplet, transferring information to Arduino. Upon moisture above a limit, the wiper initiates. The Arduino manages the wiper speed, while the LCD indicates rain intensity and wiper speed to the driver. The car powers all the components.
