An innovation for a standard intermittent windshield wiper is the concept of a smart wiper that automatically turns itself on or off and adjusts its wiping cycle according to the intensity of rain. This article describes the development of a smart automatic windshield wiper system using a fuzzy logic-based conductive rain sensor scheme. Fuzzy logic is used to compensate nonlinearities in the sensor and implement intuitive reasoning for automatic operation of the wiper. An M68HC11-based microcontroller was developed to implement and test the smart wiper concept for a car. The proposed approach can be extended to other applications related to rain detection and system actuation
