An intelligent irrigation control system based on fuzzy control was designed,considering that precise mathematic model for irrigation system is difficult.With soil moisture error as input,length of irrigation time as output,the crop's length of irrigation time was obtained through fuzzification,fuzzy inference and fuzzy decision.Wireless humidity sensor and DZK201 of Jennic company electric valve controller were used for information collection,transmission,receiving and execution.This made the installation and the deployment of each node easy,eliminated the cumbersome process of wireline access and reduced costs.
