SYNOPSIS
Auto wiper speed controller according to rain force
Objective:
The objective of the project is to design a vehicle wiper speed controller according to the rain force for minimum usage of battery to save the battery power.
System Block Diagram:
Detailed Description
Usually when rainfall starts, the driver of the vehicle has to switch on the wiper, which starts operating with its high speed which takes more power from the battery even though there is light amount of rainfall, for which the high speed rotation of wiper is not necessary. So to avoid this we can detect the amount of rainfall like lighter, moderate and heavy and then according to it the speed of the wiper can be controlled.
Here the rain force is detected first, then the wiper is switched ON automatically, then its speed is controlled by using pulse width modulator according to the rain fall.
Hardware required:
Microcontroller 89c5x
Wiper motor
Rainfall detector
MOSFET
Other semiconductors
Software Required:
Keil compiler for 8051 microcontroller.
