The aim is to design and develop a control system based an electronically controlled automotive rain operated motor is called " AUTOMATIC RAIN OPERATED WIPER" .

Rain operated motor is consists of conduction sensor (Tough sensor) circuit, Control Unit, wiper motor and glass frame. The sensor is used to detect the rain or water flow. There is any rain on the class, the sensor senses the rain or flow water and giving the control signal to the wiper motor.


We have pleasure in introducing our new project " AUTOMATIC RAIN OPERATED WIPER ", w hich is fully equipped by sensors circuit and wiper motor. It is a genuine project which is fully equipped and designed for Automobile vehicles. This forms an integral part of best quality. This product underwent strenuous test in our Automobile vehicles and it is good.

The Automatic rain operated wiper system is a fully automation project. This is an era of automation where it is broadly defined as replacement of manual effort by mechanical power in all degrees of automation. The operation remains an essential part of the system although with changing demands on physical input as the degree of mechanization is increased.

Degrees of automation are of two types, viz.

• 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

Working Principle

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"


Low cost automation project.

Free from wear adjustment.

Less power consumption

Operating Principle is very easy.

Installation is simplified very much.

To avoid other burnable interactions viz.. (Diaphragm) is not used.

It is possible to operate Manually/automatically by proving On/Off switch.

Sensor cost is very low due to conductive sensor
