Automatic rain sensing car wiper design

Abstract

In these modern times, the world is shifting towards automation whether it is automobile industry or some other. In this paper we propose automation for car wiper control. Apart from some high-end luxury vehicles all other uses manual schemes for wiper control during rainfall, which can be deadly for drivers and passengers as well as it requires proper attention to increase or decrease the wiping frequency according to rain intensity. This increases the risk of accidents; therefore, automatic rain sensing wiper system becomes a more appealing feature. Although such systems are available in market, but they are not popular due to their high cost and other limitations. The objective of this paper is to provide a cost-effective system for automatic rain sensing wiper control. This system employs a rain sensing module which senses the rain and sends an analog signal to Arduino nano which analyzes the signal and energizes the servomotor which performs the wiping operation. By implementing this automation in automobiles, we can increase the driver and passengers’ safety by a great margin.
