Abstract: The automatic wiper system is used to detect rain and activate the car's automatic wipers without requiring driver interaction. This system was developed to reduce distractions while driving and allow drivers to focus on their primary task: driving. The distraction eliminated when developing this product was adjusting the windshield wipers manually when driving in peak weather. Just a few seconds of a driver not paying attention to the road surface to adjust the gear lever while driving in bad weather conditions can lead to a car accident. The system uses a combination of impedance and rain sensors to detect rain and its intensity. The system contains a controller that takes input signals from the sensors and controls the operation of the wipers based on these input signals. The purpose of this project is to help reduce accidents caused by drivers attempting to clean their windshields. When it rains, distracting the driver from the road when turning the windshield wipers on and off. On rainy days, we have to endure water splashing onto the car's front windshield. While driving a car, the driver cannot see road traffic. So he tries to operate the window wipers, because of this he has to frequently turn the wipers on and as a result this can cause a vehicle accident. If we apply any kind of sensor on the glass to detect watering activity, the wipers will automatically work through automation. When water touches the sensor, it sends a signal to the system, thereby causing the wiper motor to move. When the sensor detects there is no water, the wipers will stop. This will reduce the weaknesses mentioned in the beginning. An additional plan of this invention is to make the windshield wipers automatically rise from the windshield when the engine is stopped.
