With this control, an effeetive step will be taken in the yield of reduetion of water consumption, reduction of laboring force, enchanement water consumption efficiency and product operation the amount of humidity should be in a specific envions of plant root. The determination beginning and ending of irrigation time and also the irrigation period is one of the effective factors for automation of irrigation systems. To measure the soil humidity and intelligent control of water consumption, the use of soil peychro meter sensor is necessary.Several sensors such as soil psychro meter, environment psychrometer, thermometer and a processor are used to evalute the intelligent control of drop irrigation system. The goal of this research is the use of experiments in a cucumber greenhouse for eight vases with different humidity. The regression equation of a microcontroller program connected to a humidity sensor has been used to design the intelligent control irrigation system. The experiments showed that the use of this sensor and microcontroller is fuitable to intelligent control of irrigation system.
