ABSTRACT
The world today is moving ahead at a very fast pace. Some of the very common examples of fast moving objects are aeroplanes, high speed cars and many more. In our everyday life we come across many fast moving vehicles and so it is very important to measure the speed of these vehicles.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. 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.
