Abstract
An intelligent rain sensor incorporates at least one hygroscopic member and a sensor that generates signals representative of its amount of expansion due to absorption of moisture. A microcontroller executes a pre-programmed algorithm that determines at least the rate of expansion and uses that information to distinguish between actual rainfall events on the one hand, and high humidity, dew or a light sprinkle on the other hand, and sends a shut off command to an irrigation controller.
