3. Introduction Automatic Rain Sensing Car Wiper Using Arduino Nano. It is an automatic screen wiper system that monitors the intensity of rainfall and controls the frequency of operation of the wiper accordingly. So as to measure the rainfall intensity, a separate rainfall module is used in the project. Depending on the data collected from the module, a servo motor is assigned to control the movements of the wiper. Our system uses rain sensor to detect rain, this signal is then processed by microcontroller to take the desired action.

5. Requirement Hardware Components Arduino Nano The Arduino Nano is the smallest microcontroller in the Arduino family and has therefore the lowest number of pins and connections. But in my opinion the Nano is very suitable for projects where you do not need a wireless connection. 2) Rain Sensor A rain sensor or rain switch is a switching device activated by rainfall. There are two main applications for rain sensors. The first is a water conservation device connected to an automatic irrigation system that causes the system to shut down in the event of rainfall.

6. Requirement Hardware Components IR Sensor An infrared sensor is an electronic device, that emits in order to sense some aspects of the surroundings. An IR sensor can measure the heat of an object as well as detects the motion. These types of sensors measure only infrared radiation, rather than emitting it that is called a passive IR sensor 4) Servo Motor A servomotor is a rotary actuator or linear actuator that allows for precise control of angular or linear position, velocity and acceleration. It consists of a suitable motor coupled to a sensor for position feedback. It also requires a relatively sophisticated controller, often a dedicated module designed specifically for use with servomotors.

7. Requirement Hardware Components 9V Battery The nine-volt battery, or 9-volt battery, is a common size of battery that was introduced for the early transistor radios. It has a rectangular prism shape with rounded edges and a polarized snap connector at the top. This type is commonly used in walkie-talkies, clocks and smoke detectors. Battery Cap The battery has both terminals in a snap connector on one end. The smaller circular (male) terminal is positive, and the larger hexagonal or octagonal (female) terminal is the negative contact. The connectors on the battery are the same as on the load device; the smaller one connects to the larger one and vice versa.

8. Working Principle The rain sensor works on the principle of using water for completing its circuit, so when rain falls on it its circuit gets completed and sends out a signal to the microcontroller. The microcontroller now processes this data and drives the motor IC to perform required action. The motor driver IC now drives a servomotor to simulate as a car wiper. This project is designed to build a car wiper that automatically detects the rainfall intensity and regulates the frequency of wiper operation. It is built, using Arduino UNO board. A rain sensing module is used for measuring the intensity of rainfall. And a servo motor is used for controlling the wiper movements.

10. Working A rain sensor works on the principle of conductive property of water. Rain sensor is just a small open circuit which gets closed when water falls on it and complete the circuit. The complete circuit sends a small current to the microcontroller through IR sensor which acts as a signal to turn on the servo motor which runs the car wiper. This results in automatic action of car wiper against rain.

13. Conclusion This project is designed to build a car wiper that automatically detects the rainfall intensity and regulates the frequency of wiper operation. It is built, using Arduino Nano board. A rain sensing module is used for measuring the intensity of rainfall. And a servo motor is used for controlling the wiper movements. By measuring the amount of rainfall, controller will adjust the speed of servo motor. Servo is controlled by generating PWM signal at its signal line. Initially, as the project is activated, the wiper is switched back to zero-degree position by the servo motor. The controller keeps on monitoring the signal received from the rain detector module. When the rain detector module senses rainfall, the controller checks if it crosses a threshold value set in the device. As soon as that happens, the controller triggers the servo motor which than starts to work. The strength of the signal decides the speed of the servo motor.
