Introduction

• We have pleasure in introducing our new project AUTOMATIC RAIN OPERATED WIPER, which is fully equipped by sensors circuit and wiper motor.

• It is a genuine project which is fully equipped and designed for Automobile vehicles.

• The Automatic rain operated wiper system is a fully automation project.

Automation

• Automation is the use of machines, control systems and information technologies to optimize productivity in the production of goods and delivery of services.

• Degrees of automation are of two types – Full Automation Semi Automation

• In semi automation a combination of manual effort and mechanical power is required whereas in full automation human participation is very negligible.

Need of Automation

• To achieve high safety

• To reduce man power

• To increase the efficiency of the vehicle

• To reduce the work load

• Less Maintenance cost

Objective

• The main objective here is to automate the working of a wiper.

Components

• Conductive Sensor

Conductivity sensors are designed for detection of electrically conducted liquids.

• Glass frame and Supporting Structure

• Battery

It is a device consisting of one or more electrochemical cells that converts stored chemical energy into elctrical energy.

Components (Contd.)

• Wiper Motor

The wiper motor used here is a D.C. motor.

• Relay

It is an electrically operated switch.They are used where it is necessary to control a circuit by a low power signal or where several circuits must be controlled by one signal.

Working Operation

• The battery supplies the power to the sensor as well as rain operated motor.

• Wiper motor is automatically ON during the time of rainfall.

• The senor is fixed in the vehicle glass. The conductive (Touch) sensor is used in this project.

• It senses the rainfall and giving control signal to the control unit.

• The control unit activates the wiper motor automatically. This operation is called “Automatic rain operated wiper”.
