RAIN SENSOR BASED AUTOMATIC WIPER: A COMPREHENSIVE REVIEW

Abstract

Working of wiper is a manual operating mechanism which requires to be switched on to remove rain water on the screen. This does not only require driver’s attention, but also, causes a certain level of discomfort to the driver and serves as a source of distraction which increases the risk of accidents. To offer ease to the driver and essentially reduce the risk of accidents, an automatic water sensing device has become a necessity. While such a device is available in the market, its high cost and other such limitations have made it less popular in the industry. A water sensor, a microcontroller and a driver integrated circuit (IC) are the major components used in the construction and seamless working of the proposed device. Rain water is quickly and precisely detected by the rain sensor which then transmits the signal to the second component i.e. microcontroller which in turn energizes the driver IC to switch the required motion of the wipers on using motor. This device converts manual operation to a smooth automatic one.
