Automatic Rain Operated Wiper System

Automatic Wiper System in luxury cars where Windshield Wiper automatically gets activated when there is Rain or if there is some water on the windshield. Electronic Wiper is very common device that is attached in every car to wipe the water on the windshield during the rain. But generally they are manually operated and we need to switch them ON manually. But today we are going to build Automatic Rain Operated Wiper System. This circuit automatically detects the rainfall and activates the wiper to clear the windscreen. Today’s car wipers are manual systems that work on the principle of manual switching. So here we propose an automatic wiper system that automatically switches ON detecting rain and stops when rain stops. Our project brings forward this system to automate the wiper system having no need for manual intervention. For this purpose we use rain sensor along with microcontroller and a servo motor which acts as wiper. Our system uses rain sensor to detect rain, this signal is then processed by microcontroller to take the desired action. The rain sensor works on the principle of using water for completing its circuit, so when rain falls on its circuit gets completed and sends out a signal to the microcontroller. The microcontroller now processes this data and servomotor acts accordingly. When the rain drops on the sensor is high then the wiper will move fast and if less the speed of wiper will reduce.
