This project aims to develop an automatic wiper system using mechanical and electronic components. It is known as an “Automatic Rain-Operated Wiper System” and is controlled by sensors and a microcontroller. The main advantage of this system is that it automatically activates the wiper when raindrops are detected by the sensor, eliminating the need for the driver to manually operate the wiper switch. The sensor detects moisture or raindrops when they hit the sensor surface.
The system is designed using an 8051 microcontroller and operates automatically after being activated for the first time. The working principle is based on the rate of water flow collected in a cup. Depending on the flow rate and the volume of water, the system adjusts the wiper to three different speed levels.
The mechanical setup controls the motor that drives the wiper. By using this system, the driver is relieved from manually controlling the wiper, as it functions automatically based on sensor input and controller logic.
About this project
The Automatic Rain-Operated Wiper System is a fully automated project. We live in an era of automation, which can be broadly defined as the replacement of manual effort with mechanical power across various levels of mechanization. While automation reduces the need for physical input, the operation remains an essential part of the system, adapting to changing demands as the degree of automation increases.
A windscreen wiper, or windshield wiper, is a device used to remove rain and debris from the windshield. Almost all motor vehicles—including cars, trains, aircraft, and watercraft—are equipped with wipers, making them an essential safety feature.
A typical wiper consists of an arm that pivots at one end, with a long rubber blade attached at the other. The blade moves back and forth across the glass, pushing away water. The wiper speed is usually adjustable, offering multiple continuous and intermittent settings. Most vehicles use two synchronized, radial-type wiper arms.
Moving the wiper blades rapidly across the windshield requires significant force. To generate this force, a small electric motor with a worm gear mechanism is used. The worm gear reduces the motor’s speed while increasing its torque—typically by a factor of 50. This gear reduction drives a mechanical linkage that moves the wipers back and forth efficiently.
